Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls 
1.Structure of Hot-Dip Galvanized Steel Sheet Description:


Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hotdip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.


2.Main Features of the Hot-Dip Galvanized Steel Sheet:

• Excellent process capability

• Smooth and flat surface

• Workability, durability 

• Excellent anticorrosive property

• High strength

• Good formability

• Good visual effect

5.FAQ of Hot-Dip Galvanized Steel Sheet 

We have organized several common questions for our clients,may help you sincerely:


1.How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.


2. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-30 days, but the shipment will depend on the vessel situation.

Q:What is the electromagnetic steel plate in the generator?
Silicon steel sheet is the main material of motor iron core used for conducting magnetic circuit.
Q:Which is good, z15 grade steel plate and z25 grade steel plate?
Both Z15 and Z25 are the properties of steel against lamellar tearing. Their properties are marked by the fracture shrinkage index of tensile specimens in thickness direction (15 and 25 in Z15 and Z25 are the minimum values of fracture shrinkage)
Q:How can the offset film affixed to the cold-rolled steel sheet be removed?
1, with paper towels stained with some alcohol (preferably with industrial alcohol, not to use medical also OK) wipe, and then rub a few times on the clean.2. Use acetone. Method ibid. Less and thoroughly, and best of all, it removes the residual gum quickly, easily, and more efficiently than the essence.
Q:The difference and usage of color steel sandwich panel and color profiled steel sheet
The sandwich panel consists of three parts: two upper and lower forming steel plates, the middle core plate (rock wool, polystyrene, polyurethane), thick 50mm/75mm/100mm, steel strip on both sides. Wall panels and shingles used primarily for movable rooms and various large plants.
Q:What does galvanized steel sheet "-PPGI" mean?
Applications: widely used in construction, home appliances, furniture, public facilities and transportation and other fields.
Q:What is muotileaved spring? What is the little leaf spring?
Leaf: ranging from multiple pieces of the same length, width of sheet steel by adding together. Multi leaf spring of each leaf into superposition inverted triangle shape, the top plate is the longest, the bottom plate is the shortest, piece number and supporting the weight of the bus plate, plate more thick more shorter, more rigid spring. However, when the leaf springs are used for a long time, they slide and rub each other. The relative friction between the steel plates also causes spring deformation, resulting in uneven running.
Q:P355NL1 what kind of material is the steel plate?
P355NL1 is the EU standard cryogenic quality grade steel.Its quality parameter is:Thickness 8-260mm;Tensile strength Rm630-450MPa;Yield strength: 355-295MPa;The elongation after fracture is 21-22%.
Q:What is the difference between hot rolled steel and controlled rolled steel plate? Can two plates be used interchangeably?
The rolled steel plate is used to achieve the ideal special performance by controlling the amount of deformation, deformation and temperature. Having higher added value and higher price. Interchangeable, but not a good choice!
Q:Why should the back of the steel sheet pile cofferdam be pumped after the construction of the pile cap?
The appearance of surface defects of steel sheet pile, length, width, thickness, end rectangle ratio, flatness and lock shape content of inspection, do not meet the requirements of steel sheet pile is corrected, in order to reduce the difficulties in piling process.
Q:What is called steel plate sanding process?
Sand blasting can remove the oxide surface and floating rust on the surface of steel plate. It is a good process before anticorrosion painting. Sandblasting of other components may be more useful for pre coating treatment.
