Trucks reversing or turning into columns or beams, bending parts, loosening foundations or tearing the fabric.
REPAIR & REFURBISHMENT
Any original builder · Assessment across China
Vehicle impact, wind or snow damage, aged or torn fabric, leaks and ponding: whoever built the canopy, send photos or video. We assess remotely, re-measure on site, and propose patching, re-covering or structural repair with a written quote.

In short: After a membrane canopy is damaged, the usual steps are a photo assessment, an on-site re-measure, and a decision on patching, re-covering or structural repair. Qingsong repairs membrane structures built by other companies, including columns or beams bent by vehicle impact, wind and snow damage, aged or torn fabric, leaks and ponding, and rusted steel. Photo-based quotes are estimates; the written quote after the site survey prevails. We are responsible only for the parts and work we repair; existing defects elsewhere in the original structure do not transfer to us.
WHAT WE REPAIR
Common repair types. Where the structure is badly deformed or unsafe, we first assess whether to repair or rebuild.
01Trucks reversing or turning into columns or beams, bending parts, loosening foundations or tearing the fabric.

Torn fabric, bent members or a leaning structure; hazards are made safe before repair.
03Chalking, cracking or widespread tears; if the steel is sound, only the fabric is replaced.
04Small scratches, punctures or split seams can be patched before they grow.
05Water pockets, seam leaks and poor drainage are traced to the cause, then fixed.
06Rust removal, protection and repainting; loose or missing fittings tightened or replaced.

Ask a question →Yes. Send photos or video for a remote assessment, followed by a site re-measure where needed. Whether and how it can be repaired, and the cost, follow the assessment and written quote.
Usually, by replacing or straightening bent columns or beams and patching or replacing torn fabric. Damaged foundations or severe deformation need a safety assessment first.
It depends on the damage. Local tears or a few bent members can usually be repaired; if the main structure is badly deformed or leaning, repair may be neither economical nor safe.
Yes, if the steel is in good condition. We re-measure on site and check that the original connections suit the new fabric.
We re-measure on site and make the new fabric or parts to the measured dimensions.
The repair contract sets the warranty period and scope for repaired parts; unrepaired parts of the original structure are not covered.
Yes, on request: the repair quotation, before-and-after photos and repair records. The insurer or responsible party decides the claim; we do not handle claims.
