Production standard:
Hot dipped Highway galvanized
Hot dipped Highway galvanized + PE powder coated
Hot dipped Highway galvanized + static electricity spraying sted beam barrier
Hot dipped Highway Guardrail corrugated beam barrier
● Description:
Hot dipped highway guardrail corrugated beam barrier is the product based on cold bent steel sheet and welded steel pipe, then hot dip highway guard rail the inside and outside surface to make them adhered together tightly with long-term stability.
● Standard: JT/T281-1995
● Steel raw material: Q235
● Technical parameter:
| Item | Contents |
| Coating material | Zinc |
| Thickness of the coating | Not less than 61um at any point |
| Surface | Well-proportioned, same color, smooth, no steel or zinc beads, no agglomeration |
| Impact test | No breaking-off, no raised surface, no crack |
| Bend test | No crack, no breaking-off |
| Zinc coating capability | 5 times bluestone liquid dipped, no red occurrence |
| Brine spray | No corrosion occurrence |
●Capability:
The zinc coating is well-proportioned and the surface is smooth, the quality is better than the hot dipped galvanized product by hanged, it has good appearance. This kind of productions have better adsorbability, better rigidity and better anticorrosion capability.
● Production technics:
◆ Main Facility:
The unique hot dipped galvanized corrugated beam barrier automatic production line in domestic.
◆ Technics characteristic:
The corrugated beam barrier are dipped in zinc liquid for some time, the products will be coated by zinc inside and outside surface, then the surface zinc of the products are blew dried by compressed air. After some time cooling, the products surface will be coated by zinc well-proportioned. The thickness of the zinc coating could be adjusted by change the technics parameter.
Hot dipped Highway galvanized + PE powder coated corrugated beam barrier
● Description:
PE Powder coated beam barrier is the product based on cold bent steel sheet and welded steel pipe, firstly hot dip galvanizing and then powder coated inside and outside surface to make them adhered together tightly with long-term stability.
● Standard: JT/T281-1995 GB/T18226-2000
● Steel raw material: Q235
● Capability:
The beam barrier is dipped and the surface covered by floating PE powder. The PE material has good anticorrosion capability, and good extensibility at low temperature, under normal temperature without impregnant, the degradation time will be over 100 years, so it would have much better capability used between -40℃ and 80℃.
This kind of products can not only assure the anticorrosion capability, but also beautify the environment, they are the ideal products for highway and other roads.
● Technical parameter:
| Items | Contents |
| Coating materials | PE |
| Thickness of coating | >=0.25mm / > =0.25mm |
| Appearance | Even color; smooth, without break; foam, scale |
| Needle hole | 1500 V without sparkle |
| Adhesion | No scaling with 3kg pull |
| Impact | No scaling off and breaking |
| Resistance to chemical agent | Without foam, inteneration and reducing adhesion |
| At high and low temperature | Without folds, inflation, scaling off |
| Accelerating resistance to climate | No big change, no breaking, no damage |
| Salt spray | No foam, no scaling off, no rusting |
Hot dipped Highway galvanized + static electricity spraying sted beam barrier
● Description:
Hot dipped galvanized and static electricity spraying steel beam barriers include cold formed wave-shaped steel beams and steel posts which are made of welded steel pipes. For surface treatment, first step is hot dipped galvanized process, then spray a coating of powder on inner and outer surface.
● Standard: JT/T281-1995 GB/T18226-2000
● Steel raw material: Q235
● Capability:
he coating is even and smooth. On the basis of hot dipped galvanized coating, polyster powder is coated by static electricity spraying. Good property of high adhesion, strong hardness and good color. Double anti-corrosion requirements, can beautify environment.
● Technical parameter:
