Product Description

Raw Material Minimized Spangle G550 High Strength Zinc Coated Roofing Sheet Roll

Product Description

It is produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel.After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460°C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product.

Our Advantages

1)Low iron loss, high magnetic flux strength, comes up to the international advance standard
2)Slight thickness difference between the horizontal and the longitudinal direction, promising high lamination factor
3)Processing Performance: Easily punched and cut, high dimensional accuracy
4)Insulating coating: Uniform color, good insulation, strong adhesively, high heat resistance, high imputrescibility
5)Smooth surface,no rust,no rolling marks,no cold lap,no crease,no bubble cell

Quality Control

Strict procurement process---skillful technical workers---final products inspection(resistance to corrosion,salt spray test, exposure test, machinability, thermal resistance)---standard packing

Product Application

widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100  180 grams per square metre.

Technical Processing

1) Uncoiled and sheared
2) Cleaned using a caustic solution, which can remove oil/grease, dirt, and paint
3) Entry looper to revised and then annealing furnace
4) Steel is dipped into the molten zinc bath
5) Cooled in a quench tank to reduce its temperature
6) Post treatment and crimper
