JKH Ltd - The Role of Gratings and Steelwork in Drainage Systems

April 2025

The Role of Gratings and Steelwork in Drainage Systems

When planning and executing construction projects, particularly those involving drainage systems, selecting the right materials is crucial. Drainage gratings and steelwork play an essential role in these systems, providing durability, safety, and functionality. In this blog post, we will highlight the specific products offered by JKH Ltd, including Vermin Gates, Standard Handrails, and Special Gratings & Steelwork. By the end of this article, you’ll understand why choosing the right grating and steelwork products can significantly impact the success of your project.
What are Drainage Gratings and Steelwork?

Gratings and steelwork are integral to the design and functionality of drainage systems, offering a combination of strength, durability, and efficiency. Gratings, typically crafted from robust steel, serve as covers for drainage channels, allowing water to flow through while preventing debris and larger objects from clogging the system. This open grid structure ensures efficient drainage, reduces the risk of flooding, and enhances safety by providing slip-resistant surfaces for pedestrian and vehicular traffic. Steelwork, encompassing beams, frames, and custom fabrications, provides the necessary structural support for these grates and the overall drainage infrastructure. Steel’s resilience against corrosion and environmental stressors ensures long-lasting performance, making it an ideal material for both the grating and structural components of drainage systems. Together, gratings and steelwork form a cohesive system that supports efficient water management, structural integrity, and safety in a variety of applications, from urban environments to industrial sites.
