Storage rack is a systems business: distributors and logistics projects buy a matched set of uprights, beams and decking, and they reorder the same profiles for years. Equipment for this industry wins on profile accuracy and pattern consistency, because every new upright must connect to beams already in the field.
Selective pallet racking orders uprights and beams in large repeated volumes. Inline punching and automatic cutting match this order pattern, and load ratings depend on consistent profile geometry.
E-commerce and distribution warehouses drive steady racking demand with tight project schedules. Lines running up to twenty meters per minute keep pace with installation programs.
Longspan shelving mixes uprights with shelf beams and panels in mixed batches. Recipe storage reruns each profile identically across orders.
Retail shelving uses lighter sections at zero point five to one point five millimeters, often from color-coated or PVC-laminated strip. Gentle forming protects the coated surface.
Archive and industrial storage order slotted angle and shelf sections in high volume. Simple, repeatable profiles suit dedicated lines with minimal changeover.
Wuxi Tonghe Machinery manufactures cold roll forming equipment in Wuxi, China. Since 2011, the company has built CZ purlin machines, PV bracket lines, guardrail lines, cable tray lines and custom profile lines for customers in over 30 countries. The factory covers about 30,000 m² and employs 200+ staff, including a 50+ R&D team. Production is ISO9001 certified and products carry CE marking.
About Us Certifications Engineering Cases
Pallet rack uprights, step beams and box beams, shelf panels and slotted angle. All profiles are tooled per your drawings.
Yes. Teardrop, keyhole, T-bolt and custom patterns are punched inline before forming and stored as PLC recipes. Every upright matches your beam connectors.
Strip from zero point five to two point five millimeters in carbon steel, galvanized, color-coated and PVC-laminated material. Tooling is matched to the grade.
Rack lines run at one to twenty meters per minute depending on profile and thickness. Lighter shelving sections run at the top of the range.
Lines are configured to support RMI and EN 15512 racking products, because profile accuracy and material control decide the rated loads in these standards.
Yes. Upright and beam lines run side by side with shared controls, and box beams are formed from two C sections joined on a seam station.
Send your profile drawings with dimensions, hole pattern drawings, strip thickness and grade, target output and plant voltage. We specify tooling and configuration against these items.
Rack production is a systems business. Your profiles must connect to the beams and accessories already sold with your name on them, so accuracy and pattern consistency are the real product. This guide covers the checks worth making.
Upright hole patterns lock a rack system together, and your customers reorder uprights that fit the beams they already own. A line that punches your pattern accurately, and stores it as a recipe, protects that installed base. Confirm pattern tooling and pitch accuracy before anything else.
Rack standards such as RMI and EN 15512 rate components by tested geometry, and small profile errors cut real capacity. Thin high-strength strip needs enough forming stands to shape without springback: seventeen to twenty-two stands on uprights is a reasonable baseline. Ask for sample sections and measure them against your drawings.
Uprights carry the volume, beams carry the connection, and shelving fills the catalog. Map machine count to your sales mix, and remember that box beams are two formed C sections joined on a seam station, so beam capacity runs two products deep. One supplier for the package keeps controls and wear parts common.
Retail and archive shelving runs color-coated and PVC-laminated strip, where scratched surfaces are rejected goods. Tooling surface quality and stand count decide whether the coating survives forming. State your coated-strip share when ordering, so tooling is specified for it.
Five items let us specify a rack line correctly: profile drawings with dimensions, hole pattern drawings, strip thickness and grade, target output, and plant voltage. With these confirmed, tooling, punching units and layout are quoted against your production plan.
