Prefabricated steel office building description

Commonly used steel materials and steel properties:

1) Carbon structural steel :Q235B, Q345B, etc

2) High-strength low-alloy structural steel;

3) high-quality carbon structural steel;

4) Alloy structural steel special steel

5) Special purpose steel;

6) Wall and roof materials are optional: corrugated steel, EPS sandwich panels, rockwool sandwich panels and polyurethane sandwich panels

Steel structure sheet is a kind of material widely used in the construction industry, it is favored for its high strength, light weight and convenient construction. In the classification of steel structure plates, we can see a variety of different types of materials, each with its own unique properties and application scenarios.

First of all, let's look at the type of steel structure sheet material. These types include polystyrene board sandwich board, this board with polystyrene as the core material, has good thermal insulation performance; The rock sheet sandwich board, which uses the rock sheet as the sandwich layer, enhances the structural stability of the board; Ordinary sandwich board, which is a general material, can choose different core materials according to needs; Fiberglass, a material with good chemical resistance and high strength; And steel sheet, usually used to enhance the stability and bearing capacity of the structure.

In terms of steel structure panel materials, we mainly distinguish between wall panels and roof panels. Wall panels are usually used for the facade of a building, while roof panels are used for the roof structure, both of which need to have a certain waterproof, windproof and load-bearing capacity.

The core material of sandwich board is the key factor to determine the performance of sandwich board. The EPS (expandable polystyrene) mentioned here is a common lightweight insulation material; Rockwool is known for its good fire resistance and sound insulation effect; PU (polyurethane) has excellent thermal insulation performance and bonding force; Glass wool is an environmentally friendly material with good sound absorption and heat insulation properties.

As for the thickness of the sandwich plate material, the common specifications are 50mm, 75mm, 100mm and 150mm. These sheets of different thicknesses can be selected according to the actual needs and design requirements of the building to meet different thermal insulation, insulation and bearing capacity needs.

Finally, the thickness of the single color plate material is also an important parameter, and the common thickness is 0.376mm, 0.426mm and 0.476mm. Single-color panels are usually used for the decoration of building exterior walls, which can not only provide a beautiful appearance, but also provide a certain protective effect.

The selection of steel structure plates needs to be determined according to the specific engineering needs and environmental conditions to ensure the safety, comfort and beauty of the building.
