How we work
- you send a request with drawings or a sketch and the product parameters;
- we calculate the cost and lead time;
- we make the product: cutting, bending, welding, hot-dip galvanising;
- we control quality at the stages of production;
- we hand the products over to the customer.
The typical lead time is 3–4 weeks if the product is not in stock; we confirm the exact time after the calculation.
