1250mm Hot Dipped Galvanized Steel Sheet AZ Coating Regular Spangle

1.Product Overview

AZ coated hot dipped galvalume steel sheet is used where the steel substrate needs aluminum-zinc coating protection before fabrication or installation. This product is suitable for building panels, roofing components, wall sheets, and general fabricated parts where corrosion resistance, sheet size, and surface condition need to be selected together.

The listed range covers 0.18–2.00mm thickness and 914–1250mm width, with standard cut lengths from 1500mm to 3800mm or custom length on request. The product is supplied with regular spangle and AZ50–180 coating, which positions it for sheet applications that need a metallic coated surface rather than a painted finish.

2.Technical Solution

This product uses an aluminum-zinc coated steel substrate under ASTM A792, JIS G3321, and EN 10346 routes. In practical use, service performance depends on the AZ coating mass, sheet thickness, cut-edge exposure, drainage condition, and the actual environment after installation.

The listed coating range is AZ50–180g/m2. Higher coating mass is generally more suitable when the service environment is more demanding. Lower coating mass is more suitable for lighter or better-controlled conditions. Surface treatment can be supplied as passivated, oiled, or anti-finger acrylic coating according to storage and handling requirements.

For building use, actual durability is influenced not only by coating mass but also by panel design, overlap detailing, fastener sealing, and water drainage. That is especially relevant in roofing and wall systems where exposed edges and trapped moisture can change real service behavior.

3.Specifications

4.Application

• This material is suitable for building panels, roofing components, outside wall sheets, garage doors, and window blind related sheet fabrication.
• It can also be used in household appliance parts, transportation related sheet parts, industrial enclosures, refrigeration equipment housings, and furniture sheet applications where aluminum-zinc coating protection is required before final fabrication.
• For outdoor building use, the final result depends on the coating level, panel geometry, drainage design, overlap condition, and the actual exposure environment.

5.Processing

• The sheet can be processed by cutting, bending, profiling, and general sheet metal fabrication according to the final panel design.
• For roofing and wall sheet conversion, sheet thickness and width should be selected together with the forming route and support spacing. Surface treatment should also be chosen according to storage and handling requirements, especially when the sheet will be transported or stored before installation.
• When visible surfaces are important, regular spangle should be confirmed in advance because it gives a conventional metallic appearance rather than a minimized or zero-spangle finish.

6.Advantages

• The 0.18–2.00mm range covers both lighter forming gauges and thicker fabricated sheet requirements.
• The 914–1250mm width range is practical for mainstream building sheet and panel conversion routes.
• AZ50–180 coating allows the material to be selected according to corrosion requirement instead of using one fixed coating level for all projects.
• Regular spangle provides a standard galvalume surface appearance suitable for general industrial and building use.
• Multiple surface treatments make the sheet easier to match to storage, transport, and fabrication conditions.

7.How to Choose

• Choose thickness according to the required rigidity and forming route. Thinner gauges are more suitable for easier forming, while thicker gauges are more suitable for parts that need stronger stiffness.
• Choose AZ coating level according to the service environment. Lower coating mass may be acceptable for lighter or controlled conditions, while higher coating mass is generally more suitable for more demanding outdoor environments.
• Choose passivated surface for standard storage protection, oiled surface for temporary handling protection, and anti-finger treatment when surface cleanliness and visible appearance are more important.
• Choose regular spangle when a standard metallic surface appearance is acceptable or preferred for the project.
