Next I will explain the production process for the guardrail beams. The production process mainly includes six steps: 1.Select the steel material\u00a0and Strip steel uncoiling We need to strictly select the materials for the steel beams in accordance with the standards or specific requirements of the contract.Then uncoil the steel into strips as the straight panels for the following punching work. 2.Make drawings Before production, we need to make the detailed drawings according to the actual situation, to determine the guardrail beam maximum height and minimum height. These data must be ensured as accurate as possible,otherwise the beams produced will be the substandard products. 3.Punching Then punching on the steel panels.Attention to makes the hole distance with accurate operation or it will occur that the bolts can not be fixed in the ..."}
