With more farmers moving into protected cultivation, the number of companies offering polyhouse construction has grown quickly — and so has the range in quality. Choosing the right polyhouse manufacturer in Rajasthan (or anywhere in India) makes the difference between a structure that lasts a decade and one that needs costly repairs within a year or two.
1. Check Their Manufacturing Setup
Ask whether the company fabricates its own structural frames and processes its own film and netting, or subcontracts the work out. In-house manufacturing — from steel cutting and welding to film processing — usually means tighter quality control and more accountability if something goes wrong.
2. Look For Site-Specific Engineering
A polyhouse built without a proper site survey and wind-load assessment is a structure waiting to fail in the first strong storm. A reliable manufacturer will always start with site-specific structural planning matched to your plot dimensions, crop plan and local weather conditions — not a one-size-fits-all design.
3. Ask About Material Quality
Hot-dip galvanized iron (GI) pipe resists corrosion far better than untreated steel, and UV-stabilized film lasts significantly longer than uncertified alternatives. Don’t hesitate to ask for the exact material specification — micron thickness of the film, pipe gauge and coating type — in writing.
4. Turnkey Installation vs. Supply-Only
Some companies only supply material and leave installation to local labour, which increases the risk of structural errors. A manufacturer offering true turnkey installation — design, fabrication, delivery and on-site construction by their own crews — is generally a safer, more accountable choice, especially for first-time buyers.
5. Verify Track Record And Support
Ask how many years the company has been operating, how many projects they’ve delivered, and — importantly — whether they offer support after handover. A manufacturer that disappears once the structure is built is a red flag.
