The difference between color steel plate and corrugated plate:
1. The two kinds of coating are different. Color steel plate is organic coating, and corrugated board is galvanized coating.
2. The two kinds of life is not the same, color steel plate is easy to rust; To keep it beautiful, it must be maintained every two years. Corrugated board maintenance free, long life.
Color steel plate: refers to color coated steel plate, color coated steel plate is a kind of steel plate with organic coating. Color steel plate is divided into veneer, color steel composite plate, floor bearing plate, etc. Widely used in large public buildings, public workshop, movable board room, and integrated house wall and roof.
Corrugated board is also called pressure plate, which is made of colored coated steel plate, galvanized plate and other metal plates by roller pressing and cold bending into a variety of wave type pressure plate. It is suitable for industrial and civil buildings, warehouses, special buildings, roofing, wall and inner and outer wall decoration of large-span steel structure houses. It has the characteristics of light weight, high strength, rich color and lustre, convenient construction, earthquake resistance, fire prevention, rain proof, long life, free of maintenance and so on, and has been widely promoted and applied.

What is the difference between profiled steel sheet roofing sheet and colored coated steel sheet roofing sheet?
Four materials commonly used for steel roof panels, and the differences between them:
First, color steel plate
Single layer color steel plate (color coated steel coil is used after pressing by tile press) (color steel plate, aluminum magnesium manganese plate, aluminum veneer, aluminum plastic plate).
Roof plate -- veneer (color steel plate, aluminum magnesium manganese board, aluminum veneer, aluminum plastic board).
Single layer color steel plate: color steel plate after rolling molding pressure roof board, this roof board insulation performance is very poor.
Two, roofing composite board
Site composite board - laying glass insulation cotton in the construction site, roof panel according to the length requirements can be processed on site, this roof board insulation performance is good, the whole roof can do no lap, convenient transportation.
The common practice is: color steel bottom plate + glass wool compound site + color steel roof generally have purlin exposed type and purlin hidden type two ways.
Three, sandwich roof board
Sandwich roofing board, is made up of two layers of waterproof color coating steel plate or other metal as panel, intermediate injection composite sandwich board material, commonly used materials for sandwich polystyrene, polyurethane and rock wool, the roof plate heat preservation performance is good, but due to the factory processing, when the length exceeds a certain request, it is difficult to transport.
Four, steel frame light grid plate
Steel skeleton light space, can solve the traditional sheet (e.g., choi steel) cold frost condensation phenomenon, and compared with the traditional plank (such as concrete slab) greatly reduce the construction difficulty, change and reduce the working procedure of the waterproof layer, can be integrated steel structure itself, can well realize network frame of the roof waterproof, thermal insulation, wind load and snow load, and other functions.
The steel frame and steel frame light plate (including floor slab, wall slab and roof slab) are made into integrated load-bearing plate, which can be made into multi-storey structure assembly type building. Steel frame with external hanging and internal wall panel, to achieve high-rise or super high-rise assembly building. Supporting removable partition board, refractory decorative board, so that all complex projects are processed and made in the factory, on-site fast assembly, improve the building performance, reduce the comprehensive cost.
What are the specifications of color profiled steel plate?
1) Color galvanized steel plate and aluminum zinc plate substrate specifications
Thickness: 0.25 ~ 2.3mm;
Width: 600 ~ 1270mm;
Length: usually coil, length depends on the minimum order steel.
2) Color galvanized steel plate and aluminum zinc plate commonly used specifications for construction
Thickness: 0.42, 0.48, 0.50, 0.55, 0.60mm.
3) Coating thickness
The plating thickness of galvanized steel plate is Z100, Z150, Z275, Z450
The roof is usually Z275
The plating thickness of aluminum zinc steel plate is AZ100, AZ150, AZ200 and other brands. The roof is usually used as AZ150.
