How to choose sandwich panels for steel structure buildings?

Steel structure buildings are increasingly becoming the mainstream of modern buildings, and sandwich panels play a core role in them, directly affecting the performance of buildings. This article will explore how to choose suitable sandwich panels to optimize steel structure building.

Sandwich panels, a special thermal insulation composite panel for steel structure building, is composed of panels such as color-coated steel plates, base plates and thermal insulation core materials. They are essential for improving the insulation, fire resistance, and durability of buildings.

In terms of panel and base plate selection, the commonly used materials for steel structure buildings are color-coated plates, galvanized plates, plywood, stainless steel plates and PVC. Color-coated plates are suitable for rainy and snowy areas due to their high strength, pressure resistance, beauty, and corrosion resistance. Although stainless steel plates are corrosion-resistant but expensive, PVC plates are an ideal choice for their light weight and flame retardancy, while plywood is limited by its density and easy cracking.

In terms of core materials, EPS, rock wool, glass wool, and polyurethane are commonly used in steel structure building. EPS foam boards are cheap but have poor fire resistance; polyurethane is known for its high fire resistance and thermal insulation performance but high price. Rock wool board is popular in steel structure buildings due to its fireproof performance and cost-effectiveness, while glass wool is an ideal heat dissipation, fireproof, and sound-absorbing material due to its light weight, heat resistance, and good thermal insulation performance.

In short, when choosing sandwich panels for steel structure buildings, it is necessary to comprehensively consider material performance, cost, and application environment to ensure the safety, durability, and economy of the building.
