排水沟钢模具使用度比较高，但是适合使用在国家建 设中去，只有国家建设中是缺少不了模具的，常规的情况下沟盖板钢模具使用的范围不是很广，主要的是盖板塑料模具使用的范围比较广。盖板模具种类居多，盖板塑料模具的使用较为广泛，总体市场反 应还是相当不错的，但是沟盖板钢模具在市场中的反应就不是很好了，排水沟钢模具的制作工艺相对来说还是比较简单的，但是钢模具都是经过打折，压弯，焊接等工艺制作而成的，难免有些缺点，之前盖板钢模具就出现过漏浆现象，这是比较常见的一种。

Drain steel mould is relatively high, but suitable for use in the construction of the country, not only is the lack of mould construction in the country, the scope of the use of conventional trench cover steel die case is not very wide, the main scope of cover plastic mold used more widely. The majority of types of mold, plastic mold cover plate is used widely, the overall market reaction is still quite good, but the reaction of trench cover steel mold in the market is not very good, the drainage ditch steel die production process is relatively simple, but the steel mold are discounted, bending, welding etc. made, inevitably some shortcomings, before the cover steel die appeared leakage phenomenon, which is a relatively common.
