PVC guardrail in the market sales increasing, many customers will be PVC guardrail profile produced a great curiosity, the following PVC guardrail profiles to do a simple introduction:
1, Appearance: smooth surface, flat, no sag, no impurities and other surface defects should be uniform color materials.
However, there may be some shrinkage marks, this is a normal phenomenon, in quality inspection is allowed.
2, the overall size and deviation: section size ±0.5, matching parts ±0.3.
3, the wall thickness of the profile deviation: the main wall of each section of the visual surface is 1.5mm, 1.8mm, 2.0mm,±0.2mm.
4, the straightness of the profile deviation: 1M length of the main profile of its straightness deviation should be ≤1㎜.
5, Profile density: Profile density requirements ≤1.44, the quality per metre length should be ≥ 95% of the standard quality per length.
6, Drop hammer impact strength: in 10 degrees Celsius, drop hammer impact I drop hammer quality 1000g, drop hammer height 1000㎜;π level drop hammer quality 1000g, drop hammer height 1500 ㎜, rupture on the wall of the sample number ≤ 1.
