As a professional manufacturer of highway safety products, Tongya provides several types of guardrails, posts, guardrail components, and anti-glare panels and fences. The main materials we adopt to make fence panels and components are Q235 steel and Q345 steel. Galvanized, aluminum plated, and plastic plated panels are also available.
We have three galvanized panel production lines with an overall annual output of 80,000 tons. The three aluminum-plated panel production lines can provide 60,000 tons annually; two W-beam guardrail production lines with a total annual output of 70,000 tons; one three beam guardrail production line with an annual output of 30,000 tons; one￠140 high-frequency welded pipe production line with an annual output of 60,000 tons; two automatic spray lines with total annual output of 52,000 tons and one fence panel production line with annual output 13,000 tons.
Guardrail Roll Forming Machine
The steel plates will be rolled and molded by the roll forming equipment.
Holes and bolt holes punched by the equipment are slightly bigger than the screw bolts, allowing for fine adjustments during installation and makes installation more flexible and much easier.
There are three anti-corrosive treatments in our production, namely the galvanizing, hot-dip aluminizing, and electrostatic plastic spraying processes. The molded panels are also equipped with components and parts, such as posts, offset blocks, and screw bolts, which are also galvanized. After these anti-corrosive treatments, especially the electrostatic plastic plating, the guardrails need be dried before packaging.
Proper packaging is quite important for the guardrails for it protects them from collisions during the shipment. Every road safety product we made will be well packaged before delivery.
