Anti-corrosion Mechanism

Immerse the derusted anchor bar and accessories in liquid zinc for a certain time, so that the atoms can penetrate and diffuse each other, thereby forming an iron-zinc alloy layer, which is dense, uniform, firmly bonded, bright and corrosion resistant.

Zinc is an amphoteric metal. In thermodynamics, zinc has a stable area. Hot-dip galvanizing is an electrochemical anti-corrosion method, which hinder further corrosion through insoluble chemical substances produced by interaction between zinc and concrete solution.

Product Standard

Sinorock has formulated the standard for galvanized products coatings in accordance with ISO 1461 " Hot dip galvanized coatings on fabricated iron and steel articles Specifications and test methods". The coating thickness of main products is as follows:

Featurs and Advantages

Excellent anti-corrosion properties: As zinc is an active metal, after coating surface is damaged, it will protect the steel by battery effect.
Long service life: Zinc layer is consumed very slowly in the atmosphere, so its service life far exceeds that of any other coatings.
Full protection: As immersed into hot-dip galvanizing bath, products are fully protected and anti-corrosion effect is better.
Lower price: In most cases, the hot-dip galvanizing cost is lower. Zinc coating is more durable than others, and does not require maintenance in the future.
High processing efficiency: Hot-dip galvanizing bath is simple and efficiency is higher than other coatings.
Not affect steel performance: Hot-dip galvanizing is carried out in an environment of more than 400 �¢??, and will not affect the performance and toughness of steel.

Service Life

Generally, the service life of hot-dip galvanized products is more than 50 years in most environments, and it will be different according to corrosion level of the environment.
According to ISO 12944-2 "Paints and varnishes- Corrosion protection of steel structures by protective paint systems-Part 2: Environmental classification" (equivalent to GB/T 30790.2), The table below lists the reference rates for different atmospheric-corrosivity environment categories.
