Grille en acier galvanisé avec entretoises transversales de 50 cm, classe de charge A15, pour ACO GALA G100 06304

Application and characteristics of the drainage system

This element is a key component of the ACO GALA G100 linear drainage system, specifically designed for areas with low traffic intensity. As a galvanized steel grate with transverse bars, it meets the requirements of load class A15 according to standard PN-EN 1433. This means it is capable of withstanding loads up to 15 kN, making it an ideal choice for locations where only pedestrians or light recreational vehicles move. Thanks to this solution, sidewalks, bicycle paths, school courtyards, and residential areas can be safely drained without concern for structural damage due to daily use.

It is worth noting the specific design of the transverse bars – this construction not only ensures adequate mechanical strength but also facilitates water runoff while reducing the risk of channel clogging by larger debris. For the installer, this translates into easier installation and less frequent need for preliminary cleaning. The clear width of the channel is 100 mm, allowing effective drainage of rainwater even during heavy rainfall in recreational areas.

Installation and system compatibility

The installation process of this element has been simplified by using a screw-fastened grate attachment to the crossbar. This type of connection eliminates the need for additional clips or on-site welding, significantly accelerating installation work and reducing the risk of errors during system laying. The grate, with dimensions of 500 mm in length and 130 mm in width, fits perfectly into standard GALA G100 series channels made of polymer concrete. This material is non-absorbent and frost-resistant, as confirmed by laboratory tests – ensuring that the entire system (channel + grate) maintains consistent operational properties even under harsh atmospheric conditions.

For professionals, the possibility of adapting the system to specific hydraulic requirements is also important. These channels can be equipped with a profiled bottom with a 0.5% slope, guaranteeing self-cleaning water flow even with small amounts of sediment. If the project requires full watertightness (e.g., in the case of hazardous substances), the system can be additionally sealed with special sealants. When planning an investment, it is important to remember the key dimensions: a single segment has a length of 50 cm and a construction width of 13 cm, facilitating precise adaptation to existing surfaces without the need for complex cutting or on-site modifications.

Operational benefits and durability

Choosing a galvanized steel grate directly translates into the longevity of the installation without the need for expensive materials such as stainless steel or cast iron – unless environmental conditions require it (in which case other versions are available). Galvanization protects against corrosion in typical urban and garden conditions, while the transverse bars provide stability underfoot for pedestrians, minimizing noise when walking on the surface.

Thanks to precise dimensions (construction width of 130 mm), this element easily integrates with existing asphalt surfaces or paving stones without disrupting the aesthetics of the surroundings. In case of replacement or repair of a single segment, the modular construction of the system allows for quick removal of the grate without dismantling the entire channel – simply unscrew the mounting screws. This solution will be particularly appreciated by service companies responsible for maintaining cleanliness and functionality of drainage systems in large residential complexes or public facilities.
