A yard gully, often referred to as a drain or a grating, is a recessed area designed to collect and redirect surface water away from properties and public spaces. Heavy-duty variants are specifically engineered to handle substantial volumes of water and endure the stresses of high traffic, making them suitable for both residential and commercial applications.
The design of cast iron gully grids is not just a matter of aesthetics but also functionality. Engineers and designers must consider factors such as load-bearing capacity, the size of the apertures for water ingress, and the ability to facilitate easy cleaning and maintenance. The grid pattern itself can vary, with designs often including features to enhance grip and prevent slips, especially in wet conditions. Additionally, some grids are designed to accommodate specific geographical features, such as locations prone to heavy rainfall or areas with high vehicular traffic.
