Requesting Repair for a Tensile Membrane Structure Carport: Check Your Warranty Scope Against the Contract First

When a membrane carport develops problems such as membrane surface damage or steel structure corrosion, the first step is not to call and urge someone to come and fix it. The first step is to locate the original contract and check the warranty scope and itemized clauses. What gets repaired during the warranty period, how it is repaired, and who pays are all governed by the contract terms.

What Document Governs the Warranty Scope

The governing document is the itemized warranty clauses in your contract. A tensile membrane structure carport is not covered by a single blanket warranty. The membrane fabric, the steel structure, and other components each carry their own warranty terms, and the periods and conditions may differ. When checking, start with the itemized warranty section of the contract and confirm which category your problem falls under and whether it is still within the warranty period.

Qingsong's practice is to write all itemized warranties into the contract itself, not to rely on verbal promises. When you verify your coverage, the written contract text is the only basis.

Warranty Periods for Membrane Fabric and Steel Structure

• Membrane fabric: covered by a 5-year manufacturer warranty.
• Steel structure and other components: check each item's own terms as stated in the contract.

Because these periods differ, review them separately before requesting a repair. Do not treat the whole carport as having one uniform warranty period.

Service Life and Warranty Period Are Not the Same Thing

Under normal use and maintenance conditions, a membrane structure carport has an expected service life of approximately 10–15 years. Service life is not the same as the warranty period. The membrane fabric carries a 5-year warranty; after that period, repairs can still be arranged, but how costs are shared must be handled according to the contract or through separate negotiation. Items outside the free warranty scope need to be confirmed by both parties before work proceeds.

What to Prepare Before Requesting a Repair

Before contacting the supplier, we recommend preparing:

1. The original contract or the warranty clause pages, so the itemized warranty scope and periods can be checked quickly.
2. Photographs of the affected areas, showing the damage, corrosion, or leakage location as clearly as possible.
3. A written description of the site situation, including the carport location, how long it has been in use, and when the problem appeared and how it has developed.

With these documents ready, the supplier can assess the problem and determine responsibility much faster.

Is In-Warranty Repair Always Free of Charge?

Not necessarily. A repair is handled under the contract's warranty terms only when it falls within the warranty period, within the contractually defined warranty scope, and outside the exclusions such as improper use. No supplier should promise that all problems are repaired free of charge — the specific contract terms govern. Writing clear itemized warranty clauses at signing is far more effective than arguing afterward. If you only received verbal promises at the time, they will be difficult to rely on when you check your coverage.

Questions About Your Warranty or Supply Scope?

If you are reviewing an existing contract and want clarity on warranty terms, supply scope and documentation, please get in touch. Any items that fall outside the contractual warranty scope should be discussed and agreed in advance.
