As a new material, color steel tile has very good product performance, so it is widely used in housing construction. But at the same time, in order to ensure that the product can give full play to its own efficacy, the cutting must be carried out according to the relevant standards, such as:

1、下料要放出彩鋼瓦實樣；并根據工藝要求預留制作和安裝時的焊接收縮余量及加工余量；

1. The color steel tile sample should be put out during cutting; The welding shrinkage allowance and machining allowance for fabrication and installation shall be reserved according to the process requirements;

2、鋼材平直度、直線度超差的應先矯正，后下料；

2. Steel straightness and straightness out of tolerance should be corrected before cutting;

3、柱、梁的翼板、腹板如需接料，須整板接料，采用埋弧自動焊焊接，探傷合格后再號料、切割；

3. If the flange plate and web plate of column and beam need to be connected, the whole plate shall be connected, and automatic submerged arc welding shall be adopted. After passing the flaw detection, the material shall be numbered and cut;

4、柱與梁連板及梁端板與梁間開坡口焊，梁、柱板與端板間為Ⅱ級焊縫。

4. Groove welding is conducted between column and beam connecting plate and between beam end plate and beam, and grade II welding is conducted between beam, column plate and end plate.

所以在進行彩鋼瓦的下料操作時，一定要按照標準進行，如果不按照標準下料，就會造成材料的性能減弱甚至消失，這樣就得不償失了。

Therefore, the blanking operation of color steel tile must be carried out according to the standard. If the blanking is not carried out according to the standard, the performance of the material will be weakened or even disappeared, so the gain is not worth the loss.
