What is a 55 series single-opening aluminum alloy window? How is it defined?

Understanding product positioning from English name

The English name for the 55 series single-opening aluminum alloy window is "55 profile single opening window". This name directly reveals the three core attributes of the product: series number, structural form, and material type. "55 profile" typically refers to the cross-sectional width or series code of the profile, which is a common method in the industry to distinguish different window type specifications; "single opening" clearly indicates that this is a single-opening window, meaning the window sash opens only to one side, distinguishing it from double-opening or sliding windows.

For procurement personnel, this English name serves as a fundamental information anchor for identifying product specifications, conducting international inquiries, or engaging in technical communication. In the context of residential window type configuration or project procurement, the accurate use of this name helps avoid selection deviations caused by terminology confusion.

Core profiles and wall thickness parameters

The product adopts 6063-T5 aluminum alloy profiles with a reference wall thickness of 1.4 mm. 6063-T5 is a common grade and heat treatment state for aluminum alloy profiles, where "6063" represents the alloy composition, and "T5" indicates that the profile undergoes air-cooled quenching and artificial aging treatment after high-temperature extrusion. This treatment method can ensure a certain level of strength while balancing formability and surface quality, making it a commonly used material in the field of building doors and windows.

Reference wall thickness 1.4MM is a key structural parameter of the product, which directly affects the rigidity, wind pressure resistance, and overall service life of the window frame. In engineering project procurement, wall thickness is an important indicator for evaluating whether the window type meets local building code requirements; for distribution channel product selection, 1.4MM wall thickness usually corresponds to mid-range positioning, and it is necessary to comprehensively judge based on project budget and performance requirements. It should be noted that the actual wall thickness may be adjusted due to custom requirements, and procurement should be based on the final drawings or specification sheets provided by the supplier.

How does the 55 series single-opening aluminum alloy window work? What is its basic structure?

Single opening method and hinge structure

In residential window type configuration or project procurement, the opening method of a single-opening aluminum alloy window is its most intuitive working characteristic. The 55 series single-opening aluminum alloy window is opened through hinge hinges, which is part of its basic structure. Hinge hinges are usually installed on one side of the window sash, allowing the window sash to rotate around the axis to achieve inward or outward opening.

This structure is simple and reliable, suitable for most conventional window opening sizes. For procurement personnel, understanding this helps determine whether the window type meets the project's requirements for ventilation, cleaning, and safety. For example, in kitchens or bathrooms that require frequent opening, the single-opening method is easy to operate; however, in space-constrained areas, it is necessary to confirm whether the opening direction conflicts with the interior layout.

The original English name for the 55 series single-opening aluminum alloy window is "55 profile single opening window", with a profile thickness of 1.4MM and a material of 6063-T5 aluminum alloy. These parameters directly affect the load-bearing capacity of the hinges and the stability of the window sashes. In engineering project procurement, it is necessary to confirm whether the material and installation process of the hinges match the profile to avoid deformation or abnormal noise after long-term use.

The boundary lies in that the opening angle of a single-hung window is typically limited (e.g., 90 degrees or 180 degrees), which is not suitable for scenarios requiring large-scale ventilation. If the project requires multi-directional ventilation, other window types may need to be considered.

Glass configuration and sealing system

The glass configuration has a direct impact on the thermal insulation, sound insulation, and sealing performance of windows. The reference glass configuration for the 55 series single-opening aluminum alloy window is 5+12A+5 insulating glass, where "5" represents the glass thickness (unit: millimeters) and "12A" represents the air spacer thickness of the insulating layer. This configuration provides basic performance in thermal insulation and sound insulation, suitable for residential and general commercial projects.

In engineering project procurement, procurement personnel need to determine applicability based on local climate and project standards. For example, in cold regions, hollow glass can reduce heat loss; in noisy environments, it can lower external noise transmission.

The sealing system is a supporting part of the glass configuration, typically including rubber strips and sealant. The sealing design of the 55 series single-opening aluminum alloy window relies on the profile structure and installation process to ensure air tightness and water tightness. The 'supports different wall thicknesses and glass configurations' mentioned in the product facts means that this series can adjust the glass thickness or the hollow layer to adapt to higher performance requirements.

However, it should be noted that adjustments to the glass configuration may affect the window frame load-bearing capacity and hinge load, and compatibility must be confirmed with the supplier. The boundary is that the 5+12A+5 configuration is not necessarily more stable for insulation or sound insulation; actual performance is influenced by installation quality and environmental factors. If the project has special performance requirements (such as energy-saving standards), it is recommended to provide drawings for custom confirmation.

When selecting products in distribution channels, glass configuration is a key selling point. The reference dimensions for the 55 series single-opening aluminum alloy window are 1000*1000mm, with an area of approximately 1 square meter, suitable for sample confirmation and bulk orders. Procurement personnel can use this to assess inventory and delivery schedules, but specific parameters should be based on the technical data provided by the supplier.

Overall, the product's structural design aims to balance performance and cost, making it suitable for residential window configurations and project procurement, but not for extreme climates or high-noise environments. If your project scenario does not align with these boundaries, it is recommended to consult the supplier for a more matching solution.

What problems can the 55 series single-opening aluminum alloy window solve? What scenarios is it suitable for?

Application in residential window configurations

In residential window configuration, the 55-series single-hung aluminum alloy window is primarily used to meet the basic needs of daily ventilation, lighting, and space utilization. This product adopts 6063-T5 aluminum alloy profiles with a reference wall thickness of 1.4MM, and the glass configuration is 5+12A+5; these parameters determine its applicability in conventional residential environments. The single-hung window has a simple opening method and occupies little space, making it suitable for installation in bedrooms, study rooms, and other rooms that require independent ventilation.

For residential projects, when selecting this series of window types, it is necessary to confirm whether the window opening dimensions match the product reference dimensions (1000*1000mm). If the project involves oversized window openings or special climate zones (such as high wind pressure or high humidity areas), this standard configuration may not be applicable, and a customized solution should be considered. The product supports adjustments for different wall thicknesses and glass configurations, providing flexibility for residential projects, but specific adjustments need to be confirmed with the supplier.

Project procurement and dealer channel selection

In engineering project procurement and distribution channel selection, the 55 series single-opening aluminum alloy window is suitable for batch procurement scenarios, such as standardized window type configurations for apartment buildings, hotels, or commercial buildings. Its original English name is "55 profile single opening window", facilitating international project communication. This product is suitable for sample confirmation and bulk orders, as it offers multiple series of window types to choose from, supports different wall thicknesses and glass configurations, and can adapt to various engineering needs.

For engineering projects, attention must be paid to the product's applicable boundaries during procurement: for example, in oversized dimensions or special climate zones (such as extremely cold or high-temperature regions), standard configurations may not meet performance requirements, and customized solutions are needed. When selecting products for distribution channels, based on this product's coverage of single-opening aluminum alloy window projects for residential, engineering, and distribution channels, one can proceed, but must avoid promising unverified performance such as 'more reliable sound insulation' or 'more reliable thermal insulation.' It is recommended to clarify the specific project conditions before procurement and confirm the possibility of customization with the supplier.

How to interpret the key parameters of the 55 series single-opening aluminum alloy window?

Relationship between profile thickness and strength

1.4MM wall thickness is the reference profile thickness for the 55 series single-opening aluminum alloy window, which directly relates to the basic structural strength of the window frame. In engineering selection, profile thickness is typically regarded as the first threshold for judging wind pressure resistance and durability. For the Haipai Sichuang 55 series single-opening aluminum alloy window, it adopts 6063-T5 aluminum alloy profile, and the 1.4MM wall thickness provides a structural foundation that meets the requirements of conventional residential and commercial projects.

However, wall thickness is not one of the key determining factors. The strength of the window frame also depends on the profile's cavity design, the fit of the hardware, and the installation process. In coastal areas with high wind pressure or high-rise projects, procurement personnel need to combine specific working conditions to confirm whether a thicker profile (such as 1.6MM or above) is required to meet the project's specific wind pressure resistance requirements.

Therefore, 1.4 mm wall thickness is an important reference starting point, but the final selection must be confirmed with the supplier regarding the load standards for the specific project.

Impact of glass configuration on performance

The reference glass configuration for the 55 series single-opening aluminum alloy window is 5+12A+5, which is a double-layer insulating glass unit, with each glass pane having a thickness of 5MM and an air gap thickness of 12MM in between. This configuration has clear reference value in terms of thermal insulation and sound insulation.

The thermal insulation performance of insulating glass mainly depends on the thickness and sealing of the air layer. A 12mm air layer can effectively slow down heat transfer, suitable for temperate or hot-summer and cold-winter regions, helping to reduce summer air conditioning loads and winter heating energy consumption. In terms of sound insulation, the double-glazed structure can effectively block mid-to-low frequency noise, suitable for residential and office projects in street-facing or noisy environments.

However, it should be noted that the final effect of the glass configuration also depends on the glass type (such as whether Low-E coating is used), the sealing process, and the sealing design of the window frame. 5+12A+5 is a common insulating glass configuration, but if the project has higher requirements for thermal insulation or sound insulation, it may be necessary to adjust the glass thickness, the air layer, or adopt configurations such as triple glazing with two cavities. When purchasing, it is essential to clarify the climate conditions and performance requirements of the project location with the supplier to confirm the suitability of the glass configuration.

How to determine if the 55 series single-opening aluminum alloy window is suitable for your project?

Dimensions and configurations to confirm when selecting

In residential window type configuration or engineering project procurement, to determine whether the 55 series single-opening aluminum alloy window is suitable, the first step is to check the match between the actual opening size and the product reference size. The reference size of this product is 1000*1000mm, with an area of about 1 square meter, which provides an intuitive benchmark for the project party. If your window opening size is close to or slightly larger than this reference value, it can generally be considered; if the difference is large, the feasibility of customization needs to be assessed.

Secondly, it is necessary to confirm the wall thickness and glass configuration. The profile thickness of the 55 series single-opening aluminum alloy window is 1.4MM, and the glass configuration is 5+12A+5. These parameters directly affect the structural strength, sound insulation, and thermal insulation performance of the window.

For example, a 1.4 mm wall thickness is a common engineering-grade choice, suitable for most residential and commercial projects; while a 5+12A+5 insulated glass configuration can provide basic thermal insulation and sound insulation effects. If the project has higher performance requirements, it is necessary to consult the supplier whether adjustments to the wall thickness or glass configuration are supported.

Finally, installation conditions and surrounding environment must be considered. For example, high-rise buildings may have additional requirements for wind pressure resistance performance, while humid environments require attention to the corrosion resistance of the profiles. The 55 series single-opening aluminum alloy window uses 6063-T5 aluminum alloy profiles, which have good strength and weather resistance, but specific applicability still needs to be judged based on project conditions.

If the opening size, performance requirements, or environmental conditions exceed the conventional range, it is recommended to prioritize consulting the supplier to confirm whether customization and sample confirmation are supported.

Key points for consulting suppliers

In the selection of products in distribution channels or OEM/ODM customization projects, when consulting suppliers, one should focus on product facts and project requirements, avoiding general discussions. First, clearly ask whether the 55 series single-opening aluminum alloy window supports customization according to drawings, as well as the customization cycle and process. For example, you can provide a hole size drawing and ask the supplier if they can scale or adjust based on a 1000*1000mm reference size.

Secondly, focus on confirming the sample confirmation process. Since this product is suitable for sample confirmation and bulk orders, it is recommended to request physical samples before bulk procurement to verify that the profile thickness, glass configuration, and surface treatment meet expectations. For example, samples can verify the actual feel of the 1.4MM wall thickness and the light transmittance of the 5+12A+5 glass, avoiding deviations after mass production.

In addition, it is necessary to understand the collaboration method for bulk orders. For example, ask the supplier whether they provide engineering solution support, such as installation guidance or technical documentation. The 55 series single-opening aluminum alloy windows are used for single-opening aluminum alloy window projects in residential, engineering, and distribution channel applications. Suppliers typically can provide basic technical support, but the specific scope of services needs to be clarified during consultation.

Finally, note the risk warnings and boundary conditions. For example, if the project involves special climate zones or high sound insulation requirements, it is necessary to confirm whether the product meets relevant standards or requires additional configuration. During consultation, you can request the supplier to provide past project cases or test reports to assist in judgment.

If the supplier cannot provide clear evidence, it is recommended to carefully evaluate or seek third-party verification.

Common issues and next steps for 55 series single-open aluminum windows

Does it support customization according to drawings?

In engineering project procurement or residential window type configuration, the procurement party often needs to customize based on the opening dimensions, opening direction, or special nodes in the architectural drawings. For the 55 series single-opening aluminum alloy window, one of its core capabilities is supporting customization according to drawings. This means that the supplier can produce and adjust non-standard dimensions based on the architectural drawings or detailed dimensions you provide.

Specifically, the product is based on 6063-T5 aluminum alloy profiles and supports adjustments for different wall thicknesses and glass configurations. During the customization process, you need to provide clear opening dimensions, opening direction (such as left-hand or right-hand), and glass configuration requirements. For example, the glass in the reference configuration is 5+12A+5, but it can be adjusted to other types of glass, such as Low-E glass or laminated glass, according to project requirements.

Non-standard customization may involve mold adjustments or process changes; therefore, it is recommended to confirm technical feasibility and delivery impact with the supplier at the early stage of the project.

How to choose series and wall thickness?

Select the series and wall thickness for the 55 series single-opening aluminum alloy windows, combining the specific working conditions and performance requirements of the project. This product offers multiple series of window types to choose from, with different series corresponding to different profile structures and load-bearing capacities. Wall thickness is a key parameter affecting the strength of the window frame and its sound insulation and thermal insulation performance. The reference configuration is 1.4 mm, but other wall thickness specifications can be selected based on project needs.

In engineering project procurement, if the window opening size is large or located in a high-rise building, it is recommended to choose a series with greater wall thickness to ensure structural stability. For residential window type configuration, if focusing on cost-effectiveness and conventional use, a reference wall thickness of 1.4MM is usually sufficient to meet the requirements. When selecting, the following factors need to be considered:

  • Window opening dimensionsLarger window openings require stronger profile support.
  • Usage environmentFor street-facing or high-noise areas, prioritize configurations with better sound insulation performance.
  • Budget rangeWall thickness increase may affect cost, and performance must be weighed against budget.

It is recommended to provide specific project drawings and working condition descriptions before making decisions, so that the supplier can conduct a technical evaluation to ensure that the selected series and wall thickness are suitable for actual needs.
