| Chemical Treatment |
Lessens the likelihood of humid-storage staining |
|
A dark gray surface discoloration that develops on exposed surfaces in the presence of humidity. |
|
| Oil |
Maintains the coil's bright metallic luster for extended periods, great when appearance is important for delivery. |
|
Chemical Treatment and Oil |
The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
| Dry |
Adds the protective chemical layer from humid-storage staining and the lubricity of oil for smoother forming. Dry – For clean, dry applications; transport and storage must be handled with care, ensuring low humidity. |
| Anti-finger print |
Reduces humid-storage staining and eliminates fingerprints and smudges on the finished surface. |
China Az50 Galvalume coils stand out for a set of characteristics that matter most on site and under weather:
Aluminium-zinc coating – Approximately 55% aluminium and 43% zinc for two-sided protection.
Self-healing cut edges – An Al rich layer protects the cut edges from rusting. .
Humidity salt resistance – The coating can be applied at the seaside, tropical and rainy ambient conditions.
Scratch-resistant surface – The hard coat resists handling marks and pack scuffs.
Longer service life – Superior to plain galvanized for use in roofing and cladding.
Good formability – Cold forms, bends, roll forms and deep draws without cracking or peeling.
TISI certified - is evidence of quality as per documented quality.
As a Coil Galvalume Manufacturer, Tianjin Zhanzhi Steel supplies this corrosion-resistant material across a wide range of building uses, from roof sheets to pipework:
Roof Sheets and Panels – Corrosion-resistant sheets for residential, commercial and industrial roofs.

Garages and Sheds – Low-maintenance roofing and cladding solutions for garages, sheds and workshops.
Guttering and Flashing – Long-life gutters, flashings and roof trims.
Soundproof Walls – Panels for noise barriers and acoustic walls.
Modular and Prefab Houses – Roof and wall panels for prefabricated and modular buildings.
Pipes and Ducts – Corrosion-resistant ducts and fittings for building services.
Coil Wrapped With Paper – Coils are wrapped with the moisture paper prior to wrapping.
Steel Banding – The coils are steel banded to prevent unrolling during transit.
Edge Protection – Coil edges are safe from bruising and edge damage when moving.
Pallet or Skid Loading – Coils are loaded with wood pallets or skids for easy handling.
Container Loading – Right stowage in the container at the port keep coils clean and undamaged.
Custom Packing – We can pack according to your destination requirements.
Q1: What do the characters in AZ50 mean?
A1: AZ50 is the aluzinc coating weight, around 50g/m2 for each side of the coating.
Q2: Why is it better than galvanized for roofing?
A2: The aluminium in the coatings provides superior corrosion resistance and a longer life on roofs particularly in moist or coastal environments.
Q3:What are the grades, thickness and width you can supply?
A3: We can provide grades like G550, thickness from 0.19mm, width like 914mm, and coil size as per your requirement.
Q4: Are you certified?
A4: Yes. We can supply Chinese Az50 Galvalume but not only can provide mill test certificates but also can make third-party inspections on your behalf.
Q5: Can I place an order for a trial quantity?
A5: Yes, Tianjin Zhanzhi Steel accepts trial order and Wholesale Az50 Galvalume for big project is also ok.
