Aluzinc Steel

We offer Aluzinc in 2 types
Type 1
Aluminium 55% and Zinc 45%. This material is little Expesive but give very good heat reflection and rust prevention.

Type 2
Aluminium 45% and Zinc 55%. This material is Cheaper then Type 1. Heat reflection is 9.5% less then Type 1 & Rust prevention is 12.5% less. But is better Hot Dip Galvanize steel. Rust 1.8 times and Heat Reflection 6.8 times.

Surface Finished :

REGULAR SPANGLE:
Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.
MINI SPANGLE:
The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.
ZERO SPANGLE :
The mini spangle is further skin-passed to produce the Zero Spangle surface.
