In environments where there is a potential for an explosion within GRP Housings, it is possible to control the explosion and reduce its potential for damage and harm. Explosion Relief GRP Housings are designed with integral explosion relief roofs, providing an economical and effective way to enhance safety.
The HSE offers guidelines and recommendations for using explosion relief to mitigate the effects of an explosion. They emphasize that designers should ensure appropriate measures are in place to either prevent explosions or minimize their impact. Prevention is always preferred over protection, especially when an explosion could lead to the release of toxic materials.
The wall and roof panels of our GRP Kiosks are carefully crafted to meet your specifications. Typically, these panels feature a FSC Certified / UKTR legally verified hardwood plywood core, encapsulated in fire-retardant resin and chopped strand mat fiberglass. Moreover, for larger kiosks, we add extra reinforcements, such as steel, to ensure they meet structural requirements.s.
The roof of the GRP Housing is secured to the walls using extendable brackets, which are integrated into the housing itself. In the event of an explosion, the increased internal pressure forces the roof upwards, causing the brackets to extend. The roof is engineered to limit the maximum internal pressure during an explosion to 35mbar. While the roof will lift off the GRP Housing, it remains fully secured by the extended brackets. Once the pressure is relieved, the extendable brackets guide the roof back into its original position, ensuring the explosion relief system prevents damage to the housing. All fittings are designed to securely keep the doors closed during an explosion, with the hinges remaining fully operational. For larger GRP Housings, explosion relief sections can be incorporated in place of a full roof relief, where the specification allows, to preserve the structural integrity of the housing in the event of an explosion.
Standard GRP Enclosure construction will provide an insulation U value of 2.2 W/m2/oC, Increased levels of insulation up to 0.3 W/m2/oC could be attained by incorporating encapsulated foam into the construction.
Fire retardant resin is used to form a self extinguishing laminate to BS476 Part 7 Class 2 (Surface spread of flame). Standard panels will provide a minimum 30 min Fire Resistance to BS476 Part 22. Increased levels of protection can be offered if required.
We offer a wide variety of single, double, and multi-leaf outward opening doors in numerous sizes. Our advanced manufacturing techniques enable us to position doors anywhere within the GRP Kiosk walls. These doors are built similarly to wall panels, with added steel reinforcement to prevent warping. For improved accessibility, removable or hinged transoms and removable door sills can be added. Additionally, roller shutter or uPVC doors are available upon request.
Standard fittings include vandal-resistant stainless steel hinges and automatic hold-open stays. Double doors are equipped with internal spring bolts to secure the passive door leaf. Cylinder night-latch locks come as standard, though a wide range of other door locking systems are also available.
Various levels of natural ventilation are available as integrated features in the GRP Enclosure walls or roof. We offer a range of vent types, including stainless steel louvre vents, galvanised steel louvre vents, uPVC brick vents, and aluminium powder-coated louvre vents, all supplied with internal screens. Additionally, external GRP weatherproof cowls can be fitted if required. For more details and design calculations on natural ventilation, please contact our project team.
Our standard external GRP finish is a smooth gel-coat, providing outstanding chemical and weather resistance in harsh environments. We also offer alternative external finishes, such as simulated brick and simulated stone, which are often chosen for their environmental benefits in today’s increasingly eco-conscious world. Our standard internal finish is a white fire retardant resin. Other internal finishes are available on request.
All external finishes are available in an extensive range of colours from the RAL or BS5252 range. These colours can be viewed at our supplier website:
All colours are subject to availability and approval.
We also offer non-standard external finishes as detailed below.
General arrangement drawings are provided as standard for all items, which will be delivered in AutoCAD format and emailed to the customer for approval within an agreed timeframe from the contract start. We also supply Method Statements, Risk Assessments, and Lifting Plans when required. All these documents are prepared by a qualified Appointed Person.
As part of Multi-Activity Framework Agreements we operate as Principal Designer and Principal Contractor.
We provide a range of delivery options to suit different needs. For GRP Cabinets and smaller items, we offer cost-effective courier delivery, with offloading handled by others. Larger items are delivered on our flatbed vehicles, which are equipped with rear-mounted cranes. Our fleet includes five flatbed vehicles, each up to 8m in length. All our drivers are highly experienced and fully qualified to work on Utility Sites.
Industrial GRP has a number of permanent site teams operating throughout the UK. Our site personnel hold extensive and comprehensive qualifications that cover all the diverse range of industries we service and support.
Please consult our standard fixing details for the concrete base requirements and recommendations.
In accordance with our policy of continuous development and improvement, we reserve the right to make changes in design and specification without notice.
