We invest heavily in state-of-the-art, automated production lines, ensuring high manufacturing precision and consistency. This investment forms the very 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, combining deep industry expertise with a steadfast commitment to our clients, ensuring every machine delivers exceptional value and performance.
The PBR (Purlin Bearing Rib) panel is a staple of industrial, commercial, and agricultural steel building structures. Distinguished by its high ribs (typically 1-1/4 inches high) spaced 12 inches on center, the PBR profile incorporates an extra support leg on the under-lap rib. This specialized bearing leg is a crucial structural improvement over standard R-panels; it rests directly on the purlin, providing exceptional stability during installation and fastening, preventing deformation of the panel overlap, and ensuring a tighter, weather-resistant seal.
From an engineering perspective, designing a roll former for PBR profiles requires meticulous design of the bending stations to accommodate the material's springback, especially when dealing with high-tensile steel (e.g., Grade 80 / 550 MPa yield strength). The forming sequence must distribute stress evenly across the width of the incoming sheet to prevent localized thinning, oil-canning, or cambering.
To produce consistent PBR panels that meet international building code specifications, our roll forming machines feature 18 to 24 forming stations. The progressive design of the forming stations guarantees that the steel sheet is bent gradually. We utilize premium solid steel roller materials (typically Cr12, Gr15, or D2 tool steel) that undergo rigorous heat treatment and precision CNC machining, followed by hard chrome plating (0.05mm minimum thickness). This design achieves a surface hardness of HRC 58-62, drastically reducing wear when forming abrasive galvanized or pre-painted coils.
Our machines utilize an advanced hydraulic post-shearing system. Unlike pre-cutting systems, post-cutting reduces tongue deformation and optimizes material yield. The shear blade is manufactured from Cr12MoV tool steel, vacuum quenched to sustain a long service life without burrs. The cutting cycle is coordinated with a high-speed PLC (Siemens or Mitsubishi), utilizing closed-loop feedback from rotary encoders to maintain a cutting tolerance of ±1.0mm or better on a 6-meter panel.
Industrial PLC with touchscreen interface supports multi-batch production, automated length settings, and diagnostics.
High-grade tool steel rollers, CNC turned and hard-chromed, to prevent surface scratches on pre-painted coils.
Monolithic H-beam structural steel base, stress-relieved and precision-machined, ensures vibration-free operation.

We adhere to strict, standardized quality control protocols throughout the manufacturing process, ensuring all output consistently meets specified customer specifications.
Our quality control workflow spans from raw material sourcing (verifying steel grade certificates and metallurgy) to the alignment of shafts, testing roller hardness, and checking cutting speed and accuracy. Before delivery, every machine runs continuously for a minimum of 24 hours under simulated loading conditions to ensure the structural integrity of the mechanical frames, hydraulic pumps, and electronics.
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. Whether it is remote troubleshooting via VPN interfaces on our PLC panels, providing fast-turnaround replacement rollers and cutting blades, or deploying field service engineers for onsite maintenance, XC remains dedicated to maximizing your plant uptime.
The metal building envelope industry is experiencing rapid technological evolution driven by sustainability mandates, automated building practices, and the volatility of global material supplies. Below, we examine the macro trends defining the purchase and deployment of PBR and R-panel roll forming machinery worldwide.
To reduce shipping costs and structural weight while retaining high structural design limits, building designers increasingly specify G550 (Grade 80) steel cladding. This high-strength material has a yield strength of 550 MPa, making it significantly harder to form than standard G300 structural steel. When processed through standard roll formers, G550 is highly prone to fracturing and significant springback. XC overcomes this through custom engineering our roller profiles and increasing the number of forming stations, allowing the material to flow slowly without exceeding its ultimate tensile limits.
Smart factories require machine components that communicate in real-time with Manufacturing Execution Systems (MES). Modern XC roll forming lines feature advanced sensory nodes that track motor temperature, hydraulic pressure, and linear steel consumption. Built-in IoT routers enable remote software updates and proactive maintenance alerts before mechanical failures can occur, preserving the production schedule.
PBR roofing profiles are increasingly designed to host solar photovoltaic (PV) arrays. Standard screw-down systems can damage the panels. To optimize roofing for solar brackets, roll forming systems must maintain tight tolerances on the rib dimensions, especially the top flat section of the rib, which serves as the mounting plane. XC's high-precision roll forming lines guarantee that rib tolerances remain within ±0.5mm, ensuring a reliable interface with standard solar clamping products.
