Galvanized corrugated metal sheets are a type of building material made by coating steel sheets with a layer of zinc. This zinc coating helps protect the steel sheet from corrosion and rust, making it more durable than other types of roofing materials. The corrugated steel sheets are usually made of hot-dip galvanized mild steel, cold rolled to produce a linear corrugation pattern, to increase the bending strength of the steel sheet perpendicular to the direction of the corrugation.
Gi corrugated sheet is a lightweight roofing material made of thin sheets, stiffened by corrugations,widely used in roofs and exterior walls of buildings.GI roofing sheet is favored for light weight, high strength, low cost, good earthquake resistance, fast construction and beautiful appearance. In addition,it also has good durability and corrosion resistance and can be used in a variety of construction environments, such as industrial and civil buildings, warehouses, special buildings, and large-span steel structures.

Technical of Corrugated Roofing Sheet
1.Forming type-Cold form
2.Machine-Rolling form machine
The base material is cold rolled steel,GI coil has good processing performance. The galvanized sheet coated with a zinc layer,features a smooth, flat,uniform thickness, strong adhesion, no peeling during processing, good corrosion resistance,and excellent adhesion to paint film. It can withstand high temperatures up to 315 ℃ and has excellent surface conductivity. The surface is smooth and clean, the size is accurate, the board surface is straight, the spangles are even and beautiful.

GI Coil Surface Structure
The galvanized layer of galvanized steel coil forms a barrier that prevents moisture and other corrosive substances from entering the underlying steel, making galvanized steel a resistant and rust-resistant material that can be used in a variety of applications.
Corrugated Galvanised Sheets Advantages
- Anticorrosive:17 years in heavy industrial areas.
- Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
- Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
- Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
- Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
- The change of wind pressure, humidity and temperature will not cause bending, deformation and expansion. It has strong bending and flexural resistance.
- Save time and energy:Galvanizing process is faster than other coating methods.
Galvanized Steel Quality Inspection
In the industry, the produced galvanized sheet metal are strictly undergoing several testing that is assuring the suppliers in supplying quality. The testing in the industry is conducted by the experts. The tests we usually perform is positive material identification test, hardness test, pitting resistance test, intergranular corrosion test, flattening/flaring test, mechanical test, macro/micro test, chemical test,and third-party inspections are also performed on the demand of the clients.
Galvanized Sheet Packing & Delivery
Export Seaworthy Packing:A water proof paper + An inhibitor film + A steel sheet cover with steel edge protectors and sufficientsteel straps or customized according to the need to develop different ways.
Port:Tianjing/Qingdao,or as required
Delivery Time:15 -20 Work Days,depending on the quantity
