The aluminum used stands out from the competition throughout the entire production cycle: foundries, extrusions, powder coating, anodizing, processing, etc. – who are we and what do we do?

We aren’t just a traditional producer. We order the production of doors, windows, gates, and blinds inside of a network of selected and verified suppliers in terms of production punctuality, their financial condition, and the quality of products.

We’ll choose relevant products at an affordable price, organise safe transport and we’ll deliver the product to any address in the world.

The waiting time for nonstandard PCV colors is about 4 weeks depending on the color. The production time of PCV doors is also about 4 weeks.

The distance and package dimensions or its elements have an impact on the price. The presence of e.g. a huge HS window may raise the price compared to the delivery of standard windows.We always look for the best transport option, which besides the competitive price guarantees safety and punctuality of the delivery. The more you order the more you save - we send goods from different places in one transport. The location ensures favorable delivery prices to many different places. If the transport offer won’t be satisfying enough you can send your own shipping or pick up the package in person.

The transport time depends on the month in which the package is to arrive. To most of the countries, it is something about 3 days after packing the goods. The delivery time depends on that if the transport is dedicated (The driver is going to only one client) or in the partial load (delivery to a few clients). To countries aside from UE the time is much longer. To USA it is about 30-35 days, the delivery to Africa is very similar.

5. Are my goods insured during transport?

Yes, the package is fully insured. We deliver the goods only by using certified transport companies which have OC insurance for transported goods.

It is also looking for the best solution for you in terms of value for money for transport to offered options such as the elevator or a forklift. In some countries, it happens that for example, it is much more profitable to rent a forklift at the location, than paying extra for it at the transport company.
