Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
Solar clamps require consistent clamping opening size; ordinary processing leads to bending rebound and unstable clamping force. We adopt pre-compensation bending mold + segmented stamping forming process to control rebound precisely, keep clamping opening uniform, stable clamping pressure without loose panel slipping.
Symmetric mounting holes on mid clamps are prone to offset after forming, causing difficult on-site installation alignment. We adopt one-time integrated punching & positioning fixture tooling, ensure hole pitch tolerance within ±0.15mm, quick bolt assembly on construction site, greatly improve installation efficiency.
Thin galvanized steel raw material easily appears surface unevenness after stamping. We add leveling procedure after forming, adopt graded pressure stamping technology to guarantee flatness of pressure plate surface, fit panel frame tightly without gap or local stress deformation.
Raw cutting burrs and unprotected edges cause rusting after long outdoor exposure. Full deburring & edge rounding treatment plus customized hot-dip galvanized / aluminum-zinc coated surface treatment enhance salt spray resistance, adapt harsh outdoor rain, snow, ultraviolet environment for 25+ years service life.
Complete self-operated processes: laser cutting, stamping, CNC bending, punching, deburring, galvanizing surface treatment, no outsourcing links, better cost control, full production traceability and shorter lead time.
Years of supporting solar bracket manufacturers, deeply familiar with international PV installation standards, can provide DFM structural optimization suggestions to reduce your on-site installation failure rate and total project procurement cost.
First article confirmation, in-process dimensional inspection, finished product sampling test for every order, avoid size fluctuation in mass production, support long-term framework order stable delivery.
Customizable material (hot-dip galvanized steel, aluminum alloy, stainless steel), thickness, opening size, hole position, bending structure, surface anti-corrosion treatment; custom laser engraving brand logo & packaging solutions available.
