The curtain wall industry has strict requirements for materials. As a commonly used main material for high-end curtain walls, precision steel has always been the focus of curtain wall practitioners (designers, constructors, owners, etc.) around the four cores of "safety, beauty, efficiency and economy", with a specific focus on six key questions to ensure the safety of type selection and application.
Material Performance and Safety
Curtain wall practitioners focus on verifying whether the yield strength of precision steel reaches Q355B or above, and whether the tensile strength and bending stiffness can meet the wind pressure and seismic resistance requirements of super high-rise and long-span curtain walls to avoid structural deformation. For harsh environments such as coastal areas and acid rain, they will delve into the rust resistance of surface anti-corrosion processes (galvanizing, fluorocarbon spraying, etc.) and require the salt spray test to meet the standard. At the same time, confirm whether the fire resistance limit meets the 1-2 hour specification requirements and the impact of fire protection treatment on appearance and cost.
Processing and Installation Adaptability
If hyperboloid and special-shaped modeling are involved, confirm whether precision steel can achieve ±0.1mm level precision through CNC processing, and inquire about the processing cost and cycle of arc components. Constructors pay more attention to whether the components support factory prefabrication and bolt connection to reduce on-site welding and shorten the construction period, and at the same time pay attention to whether the lightweight design is convenient for high-altitude hoisting. In addition, verify the connection reliability between precision steel and glass, stone and other panels and the thermal expansion and contraction compensation scheme.
Appearance Effect and Cost Performance
Curtain wall practitioners will pay attention to whether the surface of precision steel can achieve wire drawing, mirror and other textures, and whether it supports Pantone color card color matching to match the architectural style. In long-span projects, it is also required to refine the cross-section to reduce line of sight obstruction and achieve a minimalist effect. In terms of cost, not only the unit price difference between precision steel and ordinary steel is compared, but also the price increase range of complex processing is evaluated, and the comprehensive cost such as maintenance and transportation is calculated from the perspective of the whole life cycle.
Compliance and Supplier Services
Curtain wall practitioners will require test reports on mechanical properties, fire resistance, weather resistance, etc., and confirm compliance with industry specifications such as JGJ 102. At the same time, they pay attention to the environmental protection and recyclability of materials, whether suppliers can provide technical support such as structural calculation and node design, and clarify the delivery cycle and quality assurance policy. Angyihao Precision Steel has become a trusted choice for high-end projects by virtue of its all-dimensional advantages and perfect services, accurately matching the core needs of curtain wall practitioners.
