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 hot-dip 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 clientsmay help you sincerely: 

1.How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

2.How to guarantee the quality of the products

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

3. 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 difference between hot rolled steel and controlled rolled steel plate? Can two plates be used interchangeably?
Controlled steel plate is called controlled rolling and controlled cooling, referred to as controlled rolling and controlled cooling.
Q:Steel plate pile length, adjacent two steel plate pile joints should be staggered what position?
If the joint in the same position, such as 9+9m then need to stagger joint position,Avoid stress in one position that results in joint fracture and deformation risk.
Q:How to introduce carbon steel plate?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel. Carbon steel, also called carbon steel, refers to an iron carbon alloy with a carbon content of less than 2.11% Wc. Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.
Q:What's the difference between a spray plate and a colored steel plate?
Color steel plate, material without zinc flower leveling, hot galvanized steel coil and zinc alloy coating, steel coil and other good substrate;
Q:The differences and uses of cold rolling and hot rolling
Cold rolled forming steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:How can the steel plate of flat welding 10mm make its deformation smaller?
High technical content is: two side groove, one side of the groove is deep, one side of the groove is shallow, the depth of difference is a seam, the two sides welding at the same time, pay attention to the deep groove of this face to be in the lead.Other ways to prevent the in-plane deformation of steel plate are: back welding, skip welding and so on.
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.
Q:What does "rolled steel" mean?.
Generally refers to the thickness below 3, some enterprises have used rolling process, for example, 1.97 of the stainless steel materials market is difficult to buy, the enterprise will use 2 or 2.5 of the material rolling process processing, production of 1.97 thickness.
Q:Is the steel plate 1.5 meters wide and 2 meters wide at the same price? .
The steel plate price is generally not the width, they only according to the different material steel plate, gives you to quote the unit price.
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.
