Is Fibre Frame resistant to corrosion and environmental damage?
Fibre Frame is engineered to withstand exposure to moisture, salt, and extreme temperatures, making it ideal for coastal, humid, and challenging outdoor locations.
How strong is the Fibre Frame system?
The fibreglass composite structure offers a high strength-to-weight ratio, making components lightweight yet strong enough for demanding structural applications.
Is the system environmentally friendly?
Fibre Frame is crafted from FRP, featuring a long lifespan and reduced maintenance requirements, which contribute to lower environmental impact and promote eco-friendly construction.
Is Fibre Frame easy to install?
The lightweight nature of FRP components and the system’s comprehensive range of brackets and caps make handling and assembly straightforward, helping reduce installation time and labour.
What kind of maintenance does Fibre Frame require?
Fibre Frame is designed to be virtually maintenance-free—no repainting, sealing, or frequent repairs. This means lower life-cycle costs and less time spent on upkeep.
Can the Fibre Frame system be customised?
The system offers an extensive selection of joists, bearers, posts, brackets, and end caps, allowing for flexible designs tailored to meet the specific needs of each project.
Does Fibre Frame mimic traditional decking sub-structures?
