highway guardrail trinity factory

The highway guardrail trinity zinc steel is high temperature hot dipping zinc material. Hot dip zinc means to put high quality steel into the bath of several thousand degrees of zinc liquid.

After soaking for a certain time, zinc liquid will permeate into steel to form a special zinc steel alloy. The surface of hot dip zinc material can not be corroded for 30 years in the field without any reason in the field. Such as: high temperature zinc steel guardrail and high pressure electric tower are used in high temperature hot dipping zinc material, which has been rustproof for 30 years. It completely solves the problems of antirust, beauty and safety for many years.

The zinc highway guardrail trinity accessories use the modified high strength engineering nylon with a long service life of up to 50 years. Its strength and hardness are much higher than that of ordinary steel. Each square meter of zinc steel guardrail can bear the pressure above 183MPA, and the tensile force of 2729MPA can bear the best points of high temperature under 220 centigrade.

Zinc highway guardrail trinity is made of zinc alloy, which is not easy to rust. It replaces the rotten iron dishes on the market now, and the anti-rust measures are carried out every year.

The combination of zinc alloy material and hi-tech baking paint confirms the new concept of green environmental protection.

Through the advanced technology of the pipeline high temperature paint, zinc steel guardrail paint surface high temperature resistant, sun - resistant, rain - resistant, corrosion - resistant, not easy to peel, and the wall pollution.

Simple assembly, through years of market exploration, innovation, reform, zinc steel fence and its accessories to a certain degree of maturity.

One cent of the price of one point is an everlasting reason for every commodity. The balcony guardrail produced by Hongda has more than 20 complicated processes. Every process can improve the quality of the product. The galvanizing pretreatment of zinc steel profiles includes alkaline degreasing, pure water cleaning, acid rust removal, two water washing and acid base. And, three cleaning, zinc-rich phosphating, four cleaning, profile passivation and so on, these treatments are directly related to the steel and zinc coating, as well as the adhesion of spraying.

Application of highway guardrail

Some small scale black heart manufacturers directly save the process steps of galvanizing before processing, directly galvanizing the black pipe cloth directly, such profiles are also very easy to rust, before doing a part of the treatment, some manufacturers only do rust removal, this is not qualified products, the acid extracted in the pretreatment of the acid in the acid.

If the alkalinity exceeds the standard, it makes the pipe more easily rusty, so the products produced by the small manufacturers that do not meet the standard can't be used at all. Only with the strong strength, the advanced technology manufacturers will do the whole process and produce the genuine and solid zinc and steel balcony guardrail pipe.

"It's hard to understand why what looks like something is so far away?" a contractor sighs at a dozen different zinc - steel manufacturers in front of a panel of balcony guardrails.

highway guardrail trinity in china

highway guardrail trinity is early used in highway guardrails. Zinc is easy to form oxide film with oxygen to prevent further oxidation of steel, so it will not rust without destroying the zinc layer.

highway guardrail trinity products are not more than ten years in civilian use. Good zinc steel pipes have been assembled into balcony guardrails and staircase armrest. They are not rusty for thirty years. They do not fade in twenty years. They can withstand the sun and sun and rain. The surface color is fresh and easy to clean with self cleaning ability. It is quickly accepted and welcomed by the masses, and zinc steel manufacturers are like them. After a spring rain, it has been set up in succession. Driven by interests, the quality of products is now uneven and the prices vary widely, which hides many unknown secrets.

The pretreatment of galvanized steel includes alkaline degreasing, pure water cleaning, acid rust removal, two water washing, acid alkali neutralization, three cleaning, zinc rich phosphating, four cleaning and passivation of profile. These treatments relate to the steel and zinc coating, and the adhesion of spray coating.

Without any pretreatment, some manufacturers will directly use the black tube cloth to wipe them directly, so that they will rust easily.

Reclaim powder, reclaim dust and other impurities in the powder. The color of the spray is natural and dark. It is easy to slice off the paint for a long time of sun and rain. But the average person can't distinguish it, but the price is 1/10 of the original powder.
