Light ballast system mounting solution
The carbon steel bracket system is suitable for a wide horizontal floor. The supporting system adopts hot-dip galvanized carbon steel material, so the overall stability of the bracket is strong, and the wind and snow resistance is strong. For different foundation solutions, the bracket system can be fixed to the cement foundation by means of pre-embedded anchor bolts, or it can be fixed directly to the ground by spiral piles. The system is flexible in design, diverse in structure and wide in scope.
