ST-ROF-330 and ST-ROF-AW-330 roof supports

ST-ROF-330 and ST-ROF-AW-330 square roof support feet

The ST-ROF and ST-ROF-AW roof feet are made of glass fibre-reinforced polypropylene (PP) with 300mm x 300mm square base with a central fixture compatible with a 41x41 STRUT channel.  For flat 0o roofs, the entire foot rests on the roof’s surface, thus ensuring very stable support. For sloped roofs, up to 10o, it is possible to screw in stems to adjust the slope of the foot. Maximum load for each foot is 2 200 N.

ST-ROF-AWL and ST-ROF-AWL-STR are recommended for loads of up to 130 kg per one foot. At such loads, vibration dampening is at up to 92,2%.
Anti-vibration mat for HVAC equipment

ST-ROF-MAT Vibration-damping mat and ST-ROF-AF absorbing rubber-based adjustable feet

Vibration-damping mats for roof supports and feet ST-ROF-AWL are ancillary component of ST-ROOF system. These anti-vibration mats/pads are placed directly on the roof under roof feet or supports in order to insulate vibrations and noise generated by roof-installed equipment. They also protect the roof membrane from mechanical damage. Vibration-dampening mats are made of styrene-butadiene rubber (SBR), and are available in two thicknesses: 10mm or 20mm; size: 330x330mm,  500 x 500 mm or 1000 x 1000 mm. ST-ROF-MAT anti-vibration mats can be easily cut into any shape to match the actual roof slope or the installation.

Modular frameworks can be used on a flat roof and a slightly pitched roof. The selected roof support modular framework is boxed for convenience. The carton box size is 400x400x1200. See below the list of ST-ROF-SET-H components.  

STRUT Channel Compatibility
ST-ROOF system is fully compatible with STRUT channel system. In our offer - LDBST strut channel is available in the following sizes : 21mm x 41mm and 41mm x 41mm – the later size fits ST-ROF feet perfectly. The product is available in 2, 4 and 6 meter sections as well as in thicknesses: 1.5; 1.6; 1.9; 2.0; 2.5 mm. When constructing the support frame for ventilation ducts or other roof-mounted equipment, You can easily cut the channel down to required sections on site or send us an inquiry for the customized set of roof supports  [see our standard  4 kits available from stock
].

The lateral rail can be connected to the horizontal one by means of the LDB-BE-41 coupling, which ensures good aesthetics and a sturdy coupling. In order to fasten the LDB-BE-41 to the rail, SRS steel screws are required along with PDS washers and NKS nuts. It is possible to use the SNP or SNL sliding bolts - instead of the standard nut and washer.  LDB-U coupling is used when building flat frames to support bigger items above the roof surface. They may also be used to build bridges and platforms to move above the roof surface.  Depending on the actual requirement, support structure and design, it is possible to utilize other available components of the LDB STRUT assembly system.

Application:

  1. ventilation and air handling units,
  2. chillers,
  3. heat pumps and solar panels,
  4. platforms and bridges
  5. air-conditioners and refrigerating units,
  6. ventilation and AC ducts or piping,
  7. solar panels
