Semi-trailers are manufactured on a closed line, invested in modern technology. Main beams are made from official imported steel from high quality steel plate manufacturers such as MAANSSHAN steel, POSCO,… with full Mill test quality certificates, CO, CQ origin. The details of each SMRM are cut by laser cutting technology with high precision, aesthetic cuts. It is then assembled into clusters on an optimized and highly automated production line. The product after welding is completed, will be transferred to blasting to clean the metal surface with a surface quality not lower than SA-2.5. The product is powder coated (Dip ED) then painted in a color finish with a coating warranty of up to 7 years.
