Why Robust Polytunnel Materials Are Essential for Durability and Stability

1. Why Robust Polytunnel Materials Are Essential for Durability and Stability High-grade polytunnel kits are built with durability, stability, functionality, and longevity in mind, professional polytunnel suppliers only use quality materials to withstand the different environmental stresses they are placed in and to meet the demands of intensive operations they are built to do. In contrast to lower-cost, less durable and robust polytunnels, professional-grade builds from reputable polytunnel suppliers prioritise their range of housings to demand quality materials for both the frame and covering. A focused approach ensures that all polytunnel kits provide reliable service in protecting and safeguarding crops or plants while standing strong in adverse weather conditions. This approach ensures quality of performance and hopefully minimal maintenance over time. Polytunnel companies are aware of and ensure that the various materials used in professional polytunnel kits and bespoke builds possess superior materials and are advantageous to purchasers of these effective housings.

2. Materials Used in Professional Polytunnel Kits The frame of a polytunnel is the foundation of its stability, robustness and resilience. Professional polytunnel kits and bespoke builds often use heavy-duty build materials approved by polytunnel suppliers. Galvanised Steel: One of the most common materials used for making frames. A hard and strong metal, resistant to rust and corrosion, can withstand harsh weather conditions. The galvanisation process coats the steel with a layer of zinc, which protects against rust, offering an opportunity for the structure to last many years 20 plus or more with care, even when used in cold or freezing, heavy rain and blustery wind climates. Quite often used on medium to large heavy-duty domestic or commercial single and multi- span builds that must endure high winds, heavy rain, and snow loads without any concerns. It provides a stable framework that supports heavier coverings and sizeable structures placed in open conditions. Aluminium: A lightweight reinforced material, durable and strong resistant to rust, and easy to handle, which makes it suitable for growers who want or need to move or reposition and even extend the tunnel. Flexible build for domestic and commercial growers or farmers, and those needing a secondary tunnel that can be easily relocated. Part or Full Timber Frame: Usually, for a bespoke build, a treated timber frame can be combined with metal hoops connected to the sides of the frame, which is suitable for small to medium-sized more sheltered spaces. Your local polytunnel supplier will advise you on garden or domestic polytunnel kits for those who require a cost-effective build. Professional growers opt for covers with specific properties tailored to agricultural or horticultural needs. Here is one type of cover they will often use. Quality UV-stabilised polytunnel covers are one of the most popular coverings offered by polytunnel suppliers for professional growers. The UV film applied to the covering prevents the polythene from degrading and discolouring under prolonged sun exposure, which can cause untreated covers to become brittle. The durable quality grade of thickness, with regular care and checks, can last from 5 to 8 years, depending on environmental conditions and the surroundings they are placed in. It allows for optimal light transmission while protecting crops from harmful UV rays. The cover offers a balanced and stable environment, allowing light to penetrate while reducing the risk of scorching and degradation over time. Most quality-produced polytunnel kits have this type of cover but do ask your polytunnel supplier who will provide expert advice about other options.
