The more complete the information, the faster and more accurately we can price your order. Accurate details also avoid re-quoting and mistakes in production. Here is what helps us most.
If you have a design
Send us the ventilation specification or drawings — as PDF, DWG or Excel. The specification already lists the sections, lengths and fittings, so we can price directly from it.
If you don’t have a design
- Product type — rectangular or round ducts;
- Cross-section — width × height in millimetres, or diameter;
- Length — total length for each size;
- Fittings — elbow angles, transition sizes, tees and their quantities;
- Sheet thickness — if required by the project or the client;
- Joint type — if you need a specific system;
- Delivery — city or site address and the desired date.
How to give dimensions correctly
- For rectangular ducts, state whether the size is internal or external;
- For round ducts — the nominal diameter (e.g. Ø200, Ø315);
- For elbows — the angle and, if it matters, the radius;
- For transitions — both end sizes, the length and the offset (centred or one-sided).
A sketch or photo works too
If you need a complex part and have no drawing, a hand sketch with dimensions or a photo of an existing part is enough. We will call you if anything needs clarifying. See custom parts.
What happens after you send a request
- We review the details and contact you if needed;
- We send you a price and lead time;
- Once agreed, we start production;
- We deliver the finished products to site.
