Complaint
Metal carved panel has excellent thermal insulation characteristics. Compared with traditional exterior wall thermal insulation decorative building materials, it has excellent cold resistance and thermal insulation performance. It greatly reduces the energy consumption of heating and refrigeration, thus saving energy expenditure. The product has high cost performance. The installation method is simple and fast. It is not limited by seasonal climate and geographical environment. It is suitable all year round. The significantly shortened project cycle not only speeds up the project progress, but also saves the construction cost and reduces the comprehensive cost. While achieving the effect of decoration and thermal insulation, the metal carved board minimizes the load of the outer wall and enhances the availability of space and land.
