Frequently asked questions

What kind of profile is used to fabricate steel frames?

All steel profiles are exported from Switzerland and originally they are manufactured with cold rolling method.

What is the difference between hot rolling and cold rolling methods?

Steel profiles are manufactured by 2 methods: cold rolling and hot rolling. In hot rolling process steel ingots are rolled up to temperature of 600°. When the steel cools off it shrinks non-uniformly, which gives slightly less control on the overall size and shape of a finished hot-rolled product. Hot-rolled steel typically has a scaly surface finish. In cold rolling method steel plate, sheet metal, or strip material is bended and shaped into desired cross section.

Cold-rolling steel allows for the creation of very precise shapes. Since the process is performed at room temperature, the steel will not shrink as it cools, as it does in the hot-rolled process. The exterior finish of cold-rolled steel is very desirable when aesthetics and visual appeal are a priority in your project.

Are these profiles thermally insulated?

Thermally insulated or non-thermally insulated profiles can be used. Double and triple glazing is also available.

How do you ensure corrosion protection?

For exterior applications galvanized profiles are preferred. Depending the corrosive environment where the project is located duplex paint system is applied. First layer is zinc primer and second layer is polyester / polyurethane coating.

Are steel profiles subjected to condensation?

Thermally broken steel profiles are not subjected to condensation. Uninsulated profiles might be subjected to condensation due to thermal difference between inside and outside.

Do you produce glazed fire rated doors?

We fabricate 30/60/90 min. glazed fire rated door (EI90) and 120 min. glazed fire rated partition (EI120).

What are the color alternatives?

Depending the architectural design RAL and special colors can be chosen. Powder coating or wet coating is applied.

Can we use custom hardware ?

Door and window handles can be replaced in line with the system requirements.

What is Corten steel and Corten window?

Corten means weathered steel and weathered steel is corroded until a protective barrier stops the corrosion. This corroded thin layer is also a protective layer of the steel against atmospheric conditions. Corten windows are produces from corten steel profiles.

Do you produce elements on request or send from stock?

Steel frames are produced upon order and that gives you the opportunity to customize your order in terms of size , opening type and surface finish.

Are these elements handcrafted?

Yes, all steel elements is handcrafted and that makes every single element is unique and a one-of-a-kind masterpiece.

What is your lead time?

Depending the size of the project 8-10 weeks are lead times.
