Weak design creates weak products. We prevent that by involving our QC team early on in the process.

Our people review frame structure, material performance, and assembly. Quality Engineers check inventory for cover fitting, greenhouse parts, hardware and packaging before documents are validated for mass production.

We verify greenhouse frame and materials for compliance with load bearing properties such as wind load, snow load, and service life.

Checks are customized depending on greenhouse kits types and uses. It includes windows size for airflow to volume ratio, or additional truss pipe for vertical growing.

A quality polytunnel must use materials that match agreed specifications, use condition and expected service life.

- We supply steel pipes from audited suppliers. Each batch of greenhouse pipe is checked for diameter, wall thickness, weld workmanship and galvanization thickness.

- All our greenhouse covers come from reputable agricultural film companies, and are checked against material type, density, cut size and transparency.

Each greenhouse manufacturing process is reviewed and monitored. Machine operators are responsible for sample checks. From pipe cutting, punching, bending, to tube swage we drastically reduce human error.

First Article Inspection allows us to spot workmanship defects upstream and avoid delivery delays. Because we assemble our greenhouses, we have an intimate knowledge of fittings and joints.

Covers cutting and sewing suffers no exception to the rule. Semi-automatic cutting tools and templates help us reduce margin of error, improving hothouse quality. Seam density, thread strength and workmanship are all part of multiple checks on the factory floor.

Getting the best out of packaging materials, whether it is resistance to damage, custom printing, or marking, is another critical mission for us.

The DUMPI quality program includes prevention and detection of packaging related defects such as: bad print, weak packaging, missing components or outdated print file.

We ensure that each quality polytunnel that ships complies with Client design files, and our own internal packaging standard. This includes box build, packaging material strength, box size, barcode, markings,…. There is a reason why we weight each box at packing stage.

Manual placement, hardware bags and private-label packaging are also part of our quality program. We understand that first impression during unboxing sets the foundation of a positive experience, and golden review.

DELITE reviews feedback from clients, end users, sales records and return cases.

If a model receives repeated comments about tight assembly, weak carton edges, unclear instructions or poor cover fitting, we treat it as a priority product improvement.

We also take market shifts and trends into account when possible. Together with brands and wholesalers, we make slight but meaningful improvement to our quality greenhouses for sale. We aim to bring out new selling advantages that gives the edge to our clients.
