• Main frame (column and rafter) are component that has "I" cross-section, the height of cross-section is constant or beveled.
• Secondary structural component (purlin, top wall supporting bar and wall beam) are lightweight steel bar with "Z" and "C" shaped or the cellular girder
• Steel panel shaped with the laminating machine (roof and wall panel) 

All the major and secondary structural components are cut, punching, drilling, welding, shaping and completed at AnCu factory before transferring to the construction zone. The quality of the building components are guaranteed as completely manufactured with the modern ISO ***1 - ***0 equipments and machine. At the construction zone, all the pre-engineering components are assembled with bolts.

With the fact that pre-engineering steel building are more cost-saving compares to the normal steel building because of the saving in the low loading area of the main frame (especially for building with width less than *0m and roof verge less than *0m). Furthermore, pre-engineering steel building are only using the pre-designed links and materials in which it will significantly reduces the producing and installing time.
       
The pre-engineered steel buildings can be fitted with accessories, structures such as hung floors, crane bridge and other accessories such as canopy, fascia board and dividing partition. This type of building system is extremely flexible, allowing to equip for interior to meet all functional and decorate the exterior to meet architectural aesthetic. This has made pre-engineering steel building to become a ideal building for  factories, warehouses, exhibition, supermarket ....
