Trefjar is the largest production company in Iceland specializing in fiberglass construction, we have a large factory and a large outdoor space, so we can take on production of large elements in high quantities.

We have molds in many shapes and sizes, but we can also build fish tanks and other equipment in any size, depending on the needs.

Larger tubs are manufactured in elements that are assembled on site, with either a concrete base or a fiberglass base, depending on what suits each project.

Smaller tanks are produced in one piece or several elements, depending on how the transport routes are to site.

We have produced tanks with a diameter of up to 6m that come on legs and are free standing on the floor.

We offer design and strength calculations for fish tanks and other constructions.

We offer a complete solution in the construction of steel and aluminum in cooperation with Stálorka, our subsidiary company.

We can make fixed quotes for tanks and other equipment, with transport and installation on site included.
