The global construction sector is undergoing a massive shift toward pre-engineered metal buildings (PEMB) and fast-erect steel architectures. Central to this evolution is the PBR (Purlin-Bearing Rib) panel profile. Unlike basic Ag panels or standard R panels, the PBR profile incorporates an extra purlin-bearing leg on its overlapping rib. This structural design enhancement distributes structural loads much more effectively, prevents water siphonage, and improves overall roof system integrity.
Consequently, multi-national contracting groups, infrastructure planners, and regional roll forming services are investing in high-speed, custom-engineered PBR roll forming lines. The demand spans industrial warehousing, agricultural storage complexes, retail supercenters, and modular energy plants where roofing components must endure heavy snow loads, cyclonic winds, and intense UV exposure.

As an established expert in the field, XC (Xiongchang) provides integrated roll forming solutions. Our portfolio encompasses core production machines for roofing, flooring, doors, and structural components, as well as the complete auxiliary line equipment essential for efficient operation.
Our substantial investment in state-of-the-art, automated production lines ensures manufacturing precision and consistency, forming the foundation of our product excellence. For over two decades, XC (XiongChang) has been a trusted leader in the design and manufacture of cold roll forming equipment. We combine deep industry expertise with a steadfast commitment to our clients, ensuring every machine delivers exceptional value and performance.
Thick solid steel side plates and double-welded base frames eliminate machine flex, maintaining strict shape profiles across years of heavy-duty continuous production.
Utilizing robust gear-motor assemblies combined with hydraulic shearing configurations allows our lines to run at maximum output with minimum downtime.
Advanced PLC systems featuring multi-lingual color touchscreens that store multiple production batch programs and integrate with enterprise scheduling systems.
With our dedication on a robust technical force and advanced industrial equipment, We XC aimed to provide integrated and automated systems across our production, to fulfill diverse industrial requirements, guaranteeing the highest standards of quality and performance in every machine we build.
Our engineering division designs each custom roll pass diagram using finite element software like COPRA. This ensures stress is applied gradually to the raw coil, reducing strain-hardening and eliminating oil-canning or camber problems. Our multi-stage forming process ensures that every rib conforms exactly to architectural tolerances, providing consistent laps on site.

Our solutions target the total lifecycle of sheet metal manufacturing. We do not just build metal formers; we architect complete automated production systems. This includes high-capacity decoilers, leveling devices, precise post-cut shears, and automatic stackers that decrease manual labor costs.
Custom engineered high-speed automated structural roll formers.
Comprehensive onsite installation, debugging, and employee training programs.
XC has a complete suite of detection and testing instruments, to rigorously verify product strength, durability, and reliability. We adhere to strict, standardized quality control protocols throughout the manufacturing process, ensuring all output consistently meets specified customer specifications.
Every shaft is tested for concentricity runout; rollers undergo strict dimensional checks against CAD drawings. A rigorous trial run using the customer's specified coil stock is executed before shipping. Only when the output panel matches all thickness and tolerances does the machine pass inspection.
From design to installation, XC provides comprehensive lifecycle support. We offer professional installation, commissioning, and operational training to ensure optimal setup and productivity.
Our dedicated after-sales support team delivers ongoing technical assistance and maintenance services, helping customers achieve sustained, peak operational performance. In addition, we support modular system upgrades, such as adding extra punch dies or cassette tooling sets to expand your product range.
