Roof – light control tent

We offer flexible solutions in PVC membrane. Rantex-designed roof structures for maintenance have been provided since the start of land-based farming. Successful installations along the entire coast show the long experience we have.

Material choices have been carefully chosen to achieve the perfect tensile strength by using a combinations of different technical fabrics such as PVC, polyester woven fabric, straps/ bands and tension pockets for wire etc.

Steel/ truss

High quality European manufactured steel. Hot-dip galvanized S355
The trusses are laser cut, welded and galvanized/ dipped for a smooth surface
The roof truss consists of 2 elements, which are bolted together in the centre and the vessel wall in bolt groups

Walkways, entrances, platforms and stairs in hot galvanized steel

Free span and wall mounted
Cold rolled C-profile in perfect length
Width of walkway = 800 – 1400 mm
Grid walkway with mesh width CC 34 × 37 or 34 × 75
Industrial railings: height 900-110 mm
Triangular suspension at the bottom of the walkway
Surface treatment. Hot-dip galvanized according to Fe / Zn class NS-EN ISO 1461

Ventilation and insulation

We adapt the ventilation to avoid corrosion and improve air quality.
Insulated tarpaulins can be provided for temperature and humidity control.

We tailor systems for new vessels and existing constructions

Tarpaulins are adapted to perfectly fit timber frames, walkways and portals to achieve high quality constructions that are reliable, low life-cycle costs and the opportunity to control the vessel environment in relation to light, temperature and humidity.

Installation Team

Our assembly team has extensive certified experience required to do all installations safely and in accordance with the current regulations. With professionals in the team, you can be confident that your construction needs are covered.
