Corrosion is everywhere,surface treatment=life span

The corrosion of steel can be considered as an electrochemical process that occurs in stages.It requires the simultaneous presence of water and oxygen.As long as either of the above conditions does not exist, corrosion will not occur.
The purpose of anti-corrosion is to isolate oxygen and water.
Simple and effective solution: metal coating and non-metal coating.

Important details easily overlooked

Screw----key point to your surprise.

For a long time, fasteners have been the weak link of all building structure connection. It is not the design or performance problems,but the reduction of strength and the broken caused by corrosion over time.

What is the solution??

Zinc-Tin alloy mechanical coating, patented and practical technology, with long-term excellent anti rust properties.

(Maximum drill thickness:12.5mm)

What we pursue:PERFECT!!!

A building need to be practical and also with beautiful appearance.
We focus on every detail and connection, use a variety of accessories to make the connection strong and beautiful.

Roof/Wall pipe caps water resistant flashing

World class waterproof products for pipe/hole on roof or wall. EPDM or silicone and other flexible materials are used, with excellent physical and chemical properties, simple construction, reliable performance and no any noise. The guaranteed service life is more than 20 years.

Quality control---Factory testing laboratories

There is a chemical lab and a physical lab in factory.The inspection of the goods before leaving the factory will be done by the labs.

The labs have all the equipments for steel chemical composition test, mechanical properties test, zinc thickness inspect, paint thickness inspect etc.The Ultrasonic flaw detector is used by certified inspector for Non-Destory Test (N.D.T) to check the welding quality. 

Packaging

With the patented packaging technology,the heavy steel loading process is being safe and fast.

Customer easily and safely unload the goods to ensure the goods received are intact.
