Is the making of roof truss held in field, as the making of conventional roof truss?
To guarantee its strength, light steel roof truss structures needs precision in the making. Therefore, the making involves a flat and spacious area, which is important, since lack of precision will significantly reduce its strength and can cause the collapse roof truss structure. The problem is that it is difficult to find a flat and spacious area near the project location. Therefore, the making of roof truss in the plant using prefabricator becomes an effective solution that guarantees the accuracy and thoroughness of the connector installments. Q: How do you connect light steel sections? Do you weld them? A: Due to the thinness of light steel, we cannot treat them the same as conventional thicker steel. Therefore, connecting method, such as welding, is not applicable on light steel. We had better use Self Drilling Screw (SDS) on light steel or a screw with steel-perforated tip without nuts. For light steel, it has to be a specific SDS with coarse threads under the head of the bolts,
