Explore our high-performance roll forming product lines engineered for durability, precision profiles, and structural integrity.
The PBR (Purlin Bearing Rib) panel stands as the industrial standard for structural building envelope systems globally. Unlike traditional R-panels, the PBR profile incorporates an extra extended lip—the bearing leg—that seats flush against adjacent panels and support members. This design feature prevents capillary action and significantly boosts structural load capacity, making it a critical choice for heavy-duty metal structures.
From agricultural storage in North America to commercial warehouses in Southeast Asia, industrial developers specify PBR panels to withstand extreme weather conditions. The manufacturing of these profiles requires highly specialized roll forming systems that can consistently shape high-tensile steel (up to Grade 80 / 550 MPa) without damaging surface finishes or compromising panel geometries.
As an expert OEM/ODM partner, XC designs and manufactures automated roll forming systems that achieve high throughput speeds, minimal scrap ratios, and consistent dimensional accuracy across thousands of run hours.

How XC Xiongchang leverages supply chain integration to provide competitive global advantages.
Operating from our 50,000 ㎡ manufacturing facility allows us to process metal machining, assembly, surface treatment, and PLC software configuration under one roof. This internal synergy minimizes material handling times and reduces lead-times compared to multi-vendor setups.
We utilize precision multi-axis CNC tooling centers to mill our roll forming rollers. High-precision manufacturing ensures clean profiles and helps eliminate scrap, coil wrinkling, and coating abrasion.
Every PBR forming machine is tested using customer-supplied coils prior to shipping. We run the equipment continuously to verify thermal stability, hydraulic pressure tolerance, and PLC response curves under typical operating conditions.
Our design team works alongside clients to customize forming systems. We tailor machines to fit unique voltage profiles, custom safety enclosures, specific decodier configurations, and region-specific raw material requirements.

Key technical criteria for procurement managers and factory operators.
When selecting an ODM PBR forming system, assessing technical compatibility with your raw materials is critical. PBR profiles formed from G550 (high-tensile steel) require gradual deformation curves to prevent stress fracture lines. A machine designed with fewer than 18 forming passes can overstress raw steel, leading to bent or twisted panel ends.
Key specifications to verify during procurement include:
Technical answers to common engineering, installation, and procurement questions.
An R-panel features basic trapezoidal ribs that overlap directly, suitable for simple wall paneling. A PBR-panel includes an extra extended lip (bearing leg) on the rib profile. This leg rests flat against the underlying structural purlin, providing improved mechanical support, enhanced weather tightness, and stronger fastening points for roof applications.
Yes, our forming rollers undergo CNC turning, precision grinding, heat treatment, and chrome-plating. The polished surface finish prevents paint friction damage, and the gradual deformation steps reduce mechanical stress on paint layers.
XC machines are engineered to work with standard commercial steel grades (ASTM A653 / G300, yield strength around 300 MPa) up to high-tensile metal profiles (G550/Grade 80, yield strength 550 MPa). Design configurations are adjusted depending on the specific yield profile.
Typical production speeds range between 15 and 25 meters per minute, depending on the post-cut hydraulic configuration. Standard machine lead-times range from 60 to 90 days, which includes design phases, fabrication, testing, and pre-shipment alignment.
