Zinc steel rail is a strong anti-corrosion and survive for a long time, because the zinc steel rail tedious process in the production of contains a lot of doorways, limited to the material selection, pipe processing, which will finish in the table there is a deep knowledge, take zinc galvanized steel rail surface protection layer, for instance, although the surface looks at nothing, but when you know you will feel to its amazing, let below small make up for your interpretation on zinc steel guardrail the fifteen process closely!
Trembling!!!!Zinc steel railings 15 surface treatment technology ring, guardrail manufacturer casting quality rail.
Coating protection includes the following steps:
(1) hot dip zinc: it ACTS as an electrochemical protection to prevent corrosion of steel substrate from inside and outside.
(2) steel: carbon structural steel, strong resistance to impact.
(3) zinc rich phosphating: enhancing adhesion of coating and substrate.
(4) organic zinc epoxy powder coating: excellent anticorrosive performance and friction impact performance.
(5) polyester color powder coating: stable anti-ultraviolet performance, long-term anti-fouling performance and surface self-cleaning performance.
It's just a few of them, and zinc steel guardrail 15 the process of the surface treatment of concrete are respectively loading, high frequency welding, straightening, hydraulic testing, eddy current flaw detection, gold processing, degreasing, surface finishing - heat invasion zinc - pure water spray cleaning - zinc phosphating - watch - secondary water - a clean, dry, organic zinc coating, curing epoxy - polyester color coating, curing, so has been tiny zinc steel rail has there are so many working procedure, and this is only a part of them, even the small make up for the shaking, so only the surface is not see what see,It is necessary to dig deeper to know its source and grasp its research.
Zhongshan guardrail manufacturer of zinc steel rail is not only in the aspect of noodle processing has a superb technology, also is very accomplished in other ways, so what waiting for quick to choose and buy a zinc steel rail belongs to you!
