Galvalume Steel Sheet

Through electrolytic galvanizing, a uniform and dense zinc layer is finally formed on the surface of the steel, but the mechanical properties of the material are still maintained. Electrogalvanized steel is usually sold in coil or sheet form. EG coil is a kind of material that can be cut, slitted and profiled for other purposes. The steel grade of galvanized steel consists of base metal grade, galvanized (E), galvanized layer type and weight. The electro-galvanized products based on SPCC, SPCD, SPCE, SPCF and SPCG are named SECC, SECD, SECE, SECF and SECG respectively.

Galvalume Steel Sheet Description

The production process of aluminum zinc plating is as follows:

Uncoiling-cleaning-annealing-zinc pot-cooling-air knife-straightening-post-treatment-coiling

Heat Reflection

People use it as a thermal insulation material, and its thermal reflectivity is up to twice that of galvanized steel.

Heat Resistance

Galvanized steel coil has good heat resistance and can withstand high temperatures above 300°C, which is very similar to the oxidation resistance of aluminized steel at high temperatures. Commonly used in chimney tubes, ovens, illuminators, fluorescent lampshades, etc.

Corrosion Resistance

The key to the corrosion resistance of aluminized zinc steel coil is the protective performance of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide, preventing further internal corrosion.

Economy

The density of 55% AL-Zn is smaller than that of Zn. Therefore, when the coating weight and thickness are the same, the area of the aluminum-zinc plated steel sheet is 3% larger than that of the galvanized steel sheet.

Easy to Paint

The coating material on the aluminized zinc steel plate has excellent adhesion, and can be directly coated with tar on advertising boards and common plates without pretreatment such as weathering.

TESTIMONIALS

The warehouse steel structure project in Texas, USA, used only ASTM A36 carbon steel from Jinggong. Its mechanical properties are stable, the material certification documents are complete, and the project supervisor approved it on the first attempt, saving us significant time and costs.

Jane Doe

Carbon Steel Field

"The outdoor scaffolding systems of power plants along the Southeast Asian coast are exposed to high salt spray environments year-round. Jinggong's galvanized steel has a uniform and dense coating, and its salt spray test results far exceeded expectations. After three years of inspections, no red rust was found on any of the substrates, demonstrating its convincing corrosion resistance."

John Smith

John Smith

Galvanized Steel Sector

"Our heavy mining machinery frames require extremely high-strength steel. Jinggong supplies S355J2 steel according to the European standard EN 10025-2, which has excellent impact toughness and performs robustly under extreme loads, greatly improving equipment safety."

Sarah Wilson

Steel Section

"Before cooperating with Jinggong, we were worried about whether Chinese steel could consistently meet JIS standards. In fact, every batch of SPHC cold-rolled coils they provided had chemical composition and mechanical property data that were completely consistent with the certificate. This rigor gave us complete peace of mind."

Michael Brown

Cold-Rolled Coil

"Our newly built logistics warehouse in Canada uses PPGI from Jinggong for both the roof and wall panels. The product not only meets CSA standards, but its unique weather-resistant coating design also allows the building to maintain its excellent appearance and performance under extreme cold and sun exposure."

Color-Coated Steel Sheets

"From the initial carbon steel trial order to the current comprehensive cooperation on stainless steel, galvanized steel, and color-coated steel sheets, Jinggong has proven its strength with consistently stable quality and professional service. They are not only suppliers of materials, but also our reliable partners in solving material technology problems."
