Project Description

In commercial or industrial settings, clients usually demand durable and functional heavy-weight hinges to maintain longevity and seamless operation. For heavy gates measuring 3′ x 6′ and weighing around 300 lbs, the type of hinge, the number of hinges, and the gap between gate & ground are important factors to consider.

Heavy Weight Door Challenge

In recent Waterson scenarios, A significant challenge happened when the client demand our outdoor heavy duty hinges to open beyond 90° while remaining stable. It is critical to accurately determine the necessary gap for hinge installation and the appropriate swing radius, particularly for gates that are 2″ thick and weigh around 300 lbs. Inadequate spacing or suboptimal hinges can result in sagging or complete gate failure.

Setting Gap and Hinge for Gate Stability

For the best optimal performance, the gap between gate and ground should typically be 25-50mm (1-2”) to clear any ground unevenness. However, since there are various gate sizes,  the maximum distance gap can be calculated by taking the distance between screws on the hinges (2.758″) minus the post thickness.

Four hinges are recommended for gates within the 4’x8’ specification and under 330 lbs. However, for gates exceeding this weight, a fifth hinge should be added to increase the weight capacity to 440 lbs, ensuring stability and durability.

Stainless Steel Hinges for Heavy Weight Use

Waterson offers stainless steel heavy duty hinges for heavy weight outdoor use. These heavy duty hinges are designed to support doors up to 440 lbs when a fifth non-functioning hinge is used. The hinges allow gates to open beyond 90°, meeting diverse design needs and ensuring easy access. Waterson 90 degree hinges therefore can remain in place. While doors can open further, they will be self-closing once past the perpendicular.
