Size Design of Color Steel Sandwich Panel for Warehouse

Yirong color steel sandwich panel manufacturers take you to understand which design requirements the thickness, size and quality of the sandwich panels for warehouses meet.

First, construction Conditions

Wood materials and other materials that do not meet the requirements of cleanliness standards are not used in the clean room. Various incoming materials for color steel sandwich panels are stored in a clean and dry environment with enclosures. 

The thickness, size and quality of the color steel sandwich panel must meet the design requirements or contract requirements, and have a factory inspection report. The production of color steel plates must be carried out in accordance with the jigsaw diagram and size and quantity list of the secondary design. During the production process, the number of drawings shall be followed, and the length of the ceiling plate should not exceed 5000mm.

Auxiliary materials, such as small hardware standard parts, must meet the design requirements or contract requirements, and have a factory certificate. The material and specification of the connecting section steel shall meet the design requirements, and there shall be a warranty or inspection report, and low-carbon steel should be used. The material and specifications of aluminum alloy profiles should meet the design requirements or contract requirements, and have a factory certificate.  There are enough temporary storage sites for materials and storage sites for aluminum alloy processing and semi-finished products. 

Second, core material types and performance comparison

Color steel sandwich panel core materials can be divided into two categories according to the chemical composition of their products, namely, one is organic chemical foam materials, such as polystyrene foam EPS, polyurethane foam PU, extruded polystyrene foam XPS, Phenolic foam PF, etc. The other type is inorganic fiber materials, such as rock wool board, foamed cement board, etc.

1. Polyurethane foam color steel sandwich panel PU

Polyurethane foam color steel sandwich panel is made of flame-retardant rigid polyurethane foam as the core material and color coated steel plate as the surface material. At present, metal-faced rigid polyurethane sandwich panels are widely used in industrial plants, warehouses, stadiums, civil residences, villas, prefab houses, combined cold storages and other buildings. But the disadvantage is that the reaction is carried out under the condition of high temperature and strong alkali, which requires high equipment, large initial investment, and difficult industrialization.

2. Polystyrene foam color steel sandwich panel EPS

Polystyrene is the white foam we often see. This color steel plate is cheap, water-resistant and non-deformable. Most of the mobile houses on the construction site are built with polystyrene sandwich panels, which are widely used, but polystyrene foam sandwich panels are not fireproof and have the worst thermal insulation effect.

3. Phenolic foam color steel sandwich panel PF

The phenolic foam color steel sandwich panel is a composite board with color steel as the surface material and phenolic foam as the core material. Phenolic foam is brittle, brittle, and has a certain degree of corrosiveness, and the acid remaining in the foam has a corrosive effect on metal materials.

4. Rock wool color steel sandwich panel

The rock wool color steel sandwich panel has better fire resistance, but the rock wool color steel plate is not waterproof, and it will produce toxic substances in case of fire and cause great pollution.

5. Paper honeycomb color steel sandwich panel

The paper honeycomb sandwich panel can be completely recycled and reused. It is a replacement product of polystyrene board, polyurethane, rock wool and other materials. It is widely used in electronics, hospital operating rooms, laboratories and other clean engineering fields, but the waterproof effect Poor, the price is more expensive.

6. Aluminum peak nest sandwich panel

Aluminum honeycomb color steel sandwich panel is made of aluminum honeycomb core plate, composited with special high-strength glue and color steel plate, supported by special aluminum alloy keel, heated, pressurized and cured. Compared with other sandwich panels, it is light in weight and good in straightness. It is a green and environmentally friendly building material, but the cost is the highest.
