SGCC refers to steel grades for hot-dip galvanized steel sheets and strips, specifically, hot-dip galvanized steel sheets and strips made from ordinary carbon structural steel.

A792 galvalume steel is an aluminium zinc-plated steel sheet characterised by excellent corrosion resistance and durability.

ASTM A653 galvalume steel is an alloy consisting of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The whole structure consists of aluminium-iron-silicon-zinc forming a dense tetrameric crystal. This alloy has good corrosion resistance and durability and is widely used in a variety of areas requiring protection, such as construction and automotive manufacturing.

A792 galvanized steel coil is a hot dip galvanized steel coil which conforms to ASTM A792/A792M.

PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel, colour-coated steel, coil-coated steel, colour-coated steel, and pre-painted steel sheet.

Hot dipped galvanized coil DX51D is a galvanised sheet made from mild steel as a base material and is a bending and forming grade galvanised sheet.

The coating structure of the Al-Zn alloy coated steel sheet is Zn-Al alloy, and the coating compositionis 55% Al, 43.3% Zn, and 1.6% Si. 

Aluminium-zinc corrugated sheet is a kind of pressure plate which adopts aluminium plate through roller pressing and cold bending to form various waveforms, which is suitable for industrial and civil buildings, warehouses, special buildings, large-span steel structure houses' roofs, walls and internal and external wall decorations.

Cold rolled galvanizing is a metal working process whereby cold rolled steel sheets are covered with a layer of zinc to improve their corrosion resistance and aesthetics.

G550 galvalume steel is a widely used material in construction, industry and agriculture. It is popular in the market for its excellent corrosion resistance and strength.

GI steel is a hot-dipped galvanized steel sheet that prevents corrosion by covering the sheet with a layer of zinc.

The features and uses of grey roofing steel sheets mainly include its diverse colour customization, good corrosion and scratch resistance, processing and forming properties, and wide range of applications. 

With the rapid development of technology, today's production and processing at the process level is also greatly enhanced, such as hot dip galvanizing is a common process treatment, simply look at the processed steel parts or castings, etc. immersed in molten zinc to form a layer of alloy plating, surface protection is obvious.

Compared with traditional tiles and wood, corrugated roofing sheets have many obvious advantages.

Galvanized steel coil Z275 is a type of steel sheet that has been coated with a layer of zinc on its surface.
