The SX20 automatic C/Z purlin roll forming machine solutionis the advanced evolutionary model of our classic SX10. Specially engineered for high-efficiency steel structure production, the SX20 introduces Pre-Punching (replacing post-punching) and an integrated Pre-Shearing function. This smart upgrade significantly reduces material waste, ensures high-precision hole alignment, and delivers ultimate cost-effectiveness for factory owners.

Applications
Industrial Warehouses & Manufacturing Plants
Used as robust horizontal roof purlins and vertical wall girts to support heavy cladding and withstand extreme wind loads.
Pre-Engineered Buildings (PEB)
Seamlessly integrates into PEB engineering workflows, providing standardized, pre-punched C/Z channels for rapid on-site bolted assembly.
Commercial Steel Structures
Ideal for airplane hangars, logistical distribution centers, shopping malls, and large-span sports arenas.
Agricultural Buildings
Extensively applied in the construction of prefabricated poultry farms, grain storage facilities, and livestock sheds.
Solar Ground Mounting Systems
Heavy-duty 3.0mm C-channels produced by the SX20 are widely utilized as structural posts and racking supports for large-scale solar PV arrays.
