Q235 Galvanized or Powder Coating Steel Highway Guardrail Systems for Road Safety
Highway guard rail are mainly used for separating and defining aisle ways, large work areas, walkways and inside loading docks. Guard rail provides a visual and physical barrier between traffic and work areas. It is of protection against accidents due to lift trucks or other mobile equipment in dock areas, aisles, around special equipment, or offices. Using of galvanized steel guard rails reduces costly damage to equipment and inventory. If any need, it is easy to expand or move modular system. It is suitable for indoor or outdoor use as well.
Highway guardrail is also for highway safety. Metal guard rail is fixed on the side of the roads or middle of the road, especially on curves and slopes for preventing vehicles from riding out from roads. The w beam barriers are of excellent anti-corrosion and tensile strength. So that, it is good to minimize the damage to driver and pedestrian.
It’s often need to remove guardrail temporarily for unobstructed maintenance or other access to an area. Layout flexibility and the ability to relocate barriers at minimal cost is an important factor.
Sunrise safety highway metal guard rails provide a substantial highly visual physical barrier that addressed all of these issues.
Four types and two classes of steel guard rail is provided follows:
|I—Zinc coated, 550g/m2 minimum single-spot.
II－Zinc coated, 1100g/m2 minimum single-spot.
Ⅲ－Beam of painting.
Ⅳ－Beam of corrosion resistant steel.
|Class A: Base metal nominal thickness—2.67 mm.
Class B: Base metal nominal thickness—3.43 mm.
Type I and Type II beams:
The beams may be galvanized before after fabrication.
The mass of coating shall conform to the requirements in the following table for the types specified. The mass of coating is the total amount of galvanizing on both sides of a sheet or beam, expressed as g/m2 (& oz/ft2) of sheet.
|Model||Min Check Limit Single-Spot Test||Min Check Limit Triple-Spot Test|
