What materials are used for steel roofing?

The 4 materials commonly used for steel roof panels, and the difference between them:

1.Color steel plate

Color steel plate

Single-layer color steel plate (color coated steel coil is used after being pressed by tile press) (color steel plate, aluminum-magnesium-manganese plate, aluminum veneer, aluminum composite plate).

Roofing plate – veneer (color steel plate, aluminum magnesium manganese plate, aluminum veneer, aluminum composite panel).

Single-layer color steel plate plate: to color steel flat plate after roll forming pressure roofing plate, this roofing plate heat preservation performance is very poor.

2.Roofing composite panel

On-site composite board – laying glass insulation cotton at the construction site, roof panel can be processed on-site according to the length requirements, this roof panel has good thermal insulation performance, the whole roof can be done without lap, easy to transport.

Commonly used practices are: color steel base plate + glass cotton on-site composite + color steel top plate generally have purlin exposed type and purlin hidden type two practices.

3.Sandwich Roof Panels

Sandwich roof panel – is made of two layers of waterproof color-coated steel or other metal as a panel, the middle of the injection of sandwich panel material composite, commonly used sandwich materials are polystyrene, polyurethane, and rock wool, this roof panel has good thermal insulation performance, but because of the processing in the factory, when the board length exceeds a certain requirement, the transportation is more difficult.

4.The steel skeleton lightweight space frame plate

Steel skeleton lightweight space frame plate, can solve the traditional plate (such as color steel plate) condensation frost phenomenon, and relative to the traditional plate (such as concrete plate) construction difficulty is greatly reduced, change and reduce the waterproof layer of the process, can be formed by the steel structure itself integration, can be very good to realize the net frame roof of the waterproof, heat preservation, wind load, rain, snow and snow load and other functions.

The steel structure skeleton and steel skeleton light plate (including floor, wall and roof panels) are made into integrated load-bearing panels, which can be made into multi-storey structural assembled buildings; the steel frame with external and internal wall panels can realize high-rise or ultra-high-rise assembled buildings. Matching detachable partition panels, fire-resistant decorative panels, etc., so that all complex projects are processed and produced in the factory, and quickly assembled on-site, which improves the performance of the building and reduces the comprehensive cost.
