Our company strictly controls the quality of our products, and we carry out strict inspections from construction drawings to all aspects of installation. On the one hand, all drawings must be reviewed by the National Design Institute before they can be processed. On the other hand, the processing of steel structures and membranes must be carried out in accordance with the correct process, and all welding is carried out in an all-welding process to ensure that the steel structure has sufficient strength to withstand.
