Applicant:
Hot dip Galvanized steel coils are 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 squaremeter.

Galvalume Steel Sheet in Coils

The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.

Advantage:

  • Strong corrosion resistance, 3 times that of galvanized steel sheet.
  • The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

What is galvalume steel ?

The surface of galvalume steel sheetfeatures a unique star-shape, smooth and plain, with silver color as primary colour. Its special plating structure could be well corrosive -proof.

Its lifespan normally could reach 25 years. It is as well in heat-resistant as used in 315℃ high temperature; The plating and paint film with good adhesion would be excellent in processability including punching press, shearing, and welding, etc., and also it performs well in electro-conductivity.

Features

  • Thermal Reflection:

People use it as material for heat-insulation for its thermal reflectivity as high as twice the galvanized steel sheet.

  • Heat-resistance:

The aluzinc steel sheet could bear above 300℃ high temperature with its good performance in heat-resistance, quite similar to the aluminized steel sheet’s performance in oxidation-resistance under high temperature. It is often used for chimney pipe, oven, illominator, and fluorescent lamp cover.

  • Corrosive-resistance performance:

The essential of galvalume steel coil’s corrosive-resistance lies at aluminium’s protective property. Once the zinc come under abrasion, the aluminium would form a layer of densified oxidized aluminium, preventing the interior from further corrosion.

  • Economical:

The density of 55%AL-Zn is smaller than Zn, therefore, with the same weight and thickness of coating, the galvalume steel sheet is 3% larger in area than that of galvanized steel sheet.

The coating material on the galvalume steel sheet is outstanding in its adhesiveness, which could be directly tarring on the advertising board and commonly used board with no pre-treatment such as weathering process.

  • The galvalume steel sheet’s surface is luxury in silver colored appearance.
  • Galvalume steel sheet and galvanized steel sheet are similar in performance of processability and painting.

The difference between galvanized and galvalume:

The primary difference lies at its coating layer. For the galvanized sheet, a layer of zinc material is averagely distributed on the surface of galvanized sheet, playing as a positive sheet protective to the base metal, in another word, zinc works as substitute for corrosive-proof protecting the base metal until it is torn off.

While the galvalume sheet’s surface is a coating layer consisting of 55% aluminium, 43.5% zinc and other few elements, which appears a honeycomb structure under microscopic observation. Aluminium honeycomb wraps the zinc.Under such circustances, even though the coating of galvalume also plays its protective role as positive sheet, however, such protection decrease sharply due to declining content of zinc and no easily electrolysis when zinc wrapped by aluminium.

Therefore, once the galvalume sheet is cut open, the verge of cut would be generally losing its protector and quickly go rusting. So we should cut as less as possible, once cutting happen, use anti-rusting paint or zinc-rich paint for protecting the verge, extending its lifespan.

Packaging Details:

  1. Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential.
  2. the contact points of these bands on the coil edge to be protect with edge protectors.
  3. Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped.
  4. Wooden and iron pallet can be used or as your requirements.
  5. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance.

Prepainted Galvanized Steel Sheet

PPGI is generally used for the civil and industrial engineering industry (such as roofing plate, partitions, ceiling partition, rolling door, etc.) or industrial power (such as house, cover of electrical equipment, etc.) and interior decoration.
Pre-Painted Galvanized is produced from the color coating line Input sheets are put into flushing, pickling phases and coated with an additives to enhance the adhesives, then, it is covered with the primer before it is officially painted and dried.
