High-quality prepainted steel sheets

● Usually we would recommend our customers the coating, zinc content, and base plate which match with the usage and service life of buildings.

● Color-coated steel sheet are products that using hot dipped galvanizing or galvalume steel plate as substrate after surface degreasing, parkerizing and chromating, baked with organic coatings.

● The commonly used coating materials for color-coated steel sheets are PE, SMP, HDP, PVDF etc.

● Color-coated steel sheet can be classified as general usage and structural usage steels. The specific grades are TDC51D, TDC52D, TS280GD, TS330GD, TS350GD, TS550GD.

● The coating structures usually is twice-baking-after twice-painting coat, with the coating thickness of over 20μm for the outside sheet, and 5-12μm at the back side. The current operative standards of the color-coated steel sheet include: Chinese GB/T 12754-2006, America ASTM A755 (galvanized), ASTM A792 (galvalume), Japan JIS G3322, Europe EN/10169, and South Korea KS D3506.

We will pay special attention to the following performance of prepainted steel sheets

● The type and the thickness of coating

● The hardness and glossiness of pencil

● T-bending test and impact test

● Mechanical property（yield stength,tensile strength,elongation）

● Anti-corrosion（salt fog）property

● Anti-fading and anti-pulverability property

● Anti-dust property

What's the features of our new model fireproof rock wool sandwich panel ?

Taking high-quality natural rocks such as basalt, gabbro and others as main materials, the core material of our new type fireproof rock wool sandwich panel is a kind of artificial inorganic fiber after the process of high temperature melting and fiberization with the characteristics of very low slag and dust content and non-absorbent. It is "real rockwool"!

The test shows that our new type rockwool sandwich panel possesses higher hydrophobicity comparing with conventional rock wool sandwich panel.

Advantages of the new type rock wool

● The type and the thickness of coating

● The hardness and glossiness of pencil

● T-bending test and impact test

● Mechanical property（yield stength,tensile strength,elongation）

● Anti-corrosion（salt fog）property

● Anti-fading and anti-pulverability property

● Anti-dust property

Disadvantages of conventional mineral wool/slag wool:

Due to its high dust content and low acidity coefficient,it has a strong corrosive effect on metals.
Its high hygroscopicity can lead to a sharp decline in thermal insulation performance, thus cold bridge phenomenon is easy to happen.

Advantages of the new type fireproof rockwool sandwich panel

● After a 90°rotation, the core material is vertical to the steel sheet, thus the panel's compressive strength increased by 100%.

● The vertical distribution and cross butting of core materials prevent the butting gap among core materials from existing, improve the strength while ensuring the flatness of the board surface.

● The imported high-efficiency binder with excellent fireproof performance is used on new products, and the new product binder is coated onto the steel sheet through the spraying way with a dosage up to 600g/m2 . The even and reliable bond makes the bonding rate nearly reach 100%.
