LANDSCAPING FIXED ON
s colder weather sets in and winter approaches, builders’ merchants across the country are preparing for a surge in demand for materials suited
to outdoor projects that can withstand harsh conditions, from winter-proof decking installations to durable roofing. This seasonal shift in activity means merchants must be well- versed in the screws and fixings that stand up well to all weather conditions.
According to James Robinson, sales and marketing director at Samac Fixings, rust is the primary adversary of outdoor screws, exposed to moisture from rain, humidity, and direct ground contact, leading to corrosion. “Fluctuating temperatures and UV exposure can also weaken screws by causing metal expansion and material degradation,” he says. To prevent these issues, outdoor screws must be crafted from durable materials and often include special coatings to enhance longevity. Samac Fixings’ Ruspert®

Corrosion issues coating is a
superior, multi-layered metallic finish applied to fasteners, providing exceptional protection against environmental challenges such as salt spray, chemicals, and moisture. Robinson says that this coating ensures screws resist corrosion and remain robust in high-moisture and saline environments, making them ideal for outdoor constructions like fences and decks, ensuring long-lasting performance. He adds: “Unlike outdoor screws, general-
Robinson says that merchant trade counter staff should recommend screws that offer high corrosion resistance, are designed to blend seamlessly with wood finishes and have a countersinking head to ensure a flush finish. “Professional decking screws, like the Performance Decking Range, are designed to stand strong against rust and corrosion and are a great option for decking, with countersinking heads that glide smoothly into the wood and sit flush with the boards, leaving no projections to snag unsuspecting passers-by,” he explains. “Their Type 17 Cut Point removes the need to drill pilot holes, reducing the risk of splitting wood and with TX Drive heads, these minimise the risk of the drill bit slipping and allow for a greater transfer of torque. This makes them easy to install; they can be driven into decking materials with minimal effort and a reduced risk of stripping, enabling a smoother, speedier build with less waste and frustration. Coming with ACQ Corrosion Resistant Coating they have been tested to a minimum of 1,000 hours on a salt spray test.”
Gate screws also need to be robust and durable, capable of securing large hinges and latches, even during harsh weather conditions. These screws are generally manufactured with additional coatings to improve rust resistance,

increasing their structural longevity. “With a Ruspert® coating in silver or black, our Performance Exterior Screws are perfect for affixing gate hardware and other outdoor applications,” he says. Salt spray tested to 1,500 hours and available in a range of sizes, they can withstand truly tough
conditions. These screws are designed with a Pan or Countersunk head. The large diameter of pan head screws makes them ideal for high- torque assembly jobs, while the flat underside ensures a firm hold even with enlarged holes. Countersunk screws offer a neat and secure finish, reducing potential hazards like snagging and provide an aesthetically pleasing look. Robinson says that 2024 marks the company’s 20th anniversary, and that the next stage will include a substantial warehouse expansion that will dramatically increase capacity. n

As more inclement weather approaches, the need for specialised, weather-resistant fixings for outdoor landscaping projects spikes.
purpose screws are typically designed for indoor use and do not have the necessary properties for outdoor projects. Most general screws are not made to withstand moisture and can rust when exposed to the elements, weakening the screw which can lead to structural failure.”
Decking screws are designed to fasten decking boards to frames securely, and are typically made from stainless steel or coated with a weather-resistant material to prevent rust. Many are self-tapping, meaning they can be driven into materials without the need for a pilot hole, simplifying the installation process.
