Drainage grates serve two important purposes: they allow surface water to enter a drainage channel while providing a stable covering for pedestrians, vehicles and surrounding surfaces. Their size, material and design must therefore match the drainage channel, installation environment and expected load.
ANRIN offers grates for residential properties, commercial areas, public spaces, industrial locations and heavy-traffic environments. The product range includes several nominal widths, grate lengths, materials and surface patterns. Buyers can filter products by load class, rainfall requirements, material and coating to identify a suitable channel and grate combination.
What Sizes Are Available for ANRIN Grates?
ANRIN drainage grates are primarily available in nominal widths of 100 mm, 150 mm, 200 mm and 300 mm. These measurements correspond to the channel system with which the grate is designed to be used. The appropriate width depends on factors such as the volume of water, the paved area being drained and the available installation space.
Most standard channel grates are supplied in lengths of 50 cm. Selected steel, stainless-steel and mesh products are also available in 100 cm lengths. This provides flexibility when planning short drainage runs, long paved sections or installations that require fewer grate joints.
100 mm Grates
The 100 mm nominal width is one of the broadest categories in the ANRIN range. It includes slotted, mesh, perforated, longitudinal and decorative grates. Depending on the specific product, 100 mm grates may support load classes ranging from A15 to F900.
This width is commonly considered for terraces, paths, entrances, driveways and commercial drainage channels. Available materials include ductile iron, galvanized steel, stainless steel and polyamide.
150 mm Grates
Grates with a nominal width of 150 mm provide a larger drainage opening and are available for residential, commercial and heavy-duty systems. The range includes OvalGrip, HEELGUARD, mesh, longitudinal profile and WIRE designs.
Selected 150 mm grates are available in C250, D400, E600 and F900 load classes. This makes the category relevant to areas ranging from pedestrian zones and parking areas to roads and demanding industrial sites.
200 mm and 300 mm Grates
The 200 mm range includes mesh, OvalGrip and HEELGUARD options. These wider grates are suitable for projects that require greater drainage capacity or wider channel systems.
ANRIN also provides 300 mm grates for reinforced-edge and heavy-duty channel applications. Available designs include OvalGrip and HEELGUARD ductile-iron grates, with certain models rated for D400, E600 or F900 loading.
Common ANRIN Grate Designs
The grate pattern affects appearance, water intake, walking comfort and suitability for wheeled traffic. ANRIN offers functional patterns as well as decorative options for projects where the drainage line remains visually prominent.
OvalGrip Slotted Grates
OvalGrip is available across several channel widths and materials. The elongated openings support water intake while creating a consistent linear appearance. Depending on the channel system, OvalGrip grates are available in ductile iron, polyamide and other material configurations.
Heavy-duty OvalGrip grates are also offered for load classes up to F900 in nominal widths from 100 mm to 300 mm.
HEELGUARD Grates
HEELGUARD grates use narrower openings intended to provide a more suitable surface for pedestrian areas and locations where narrow footwear, small wheels or mobility equipment may pass across the drainage line.
The design is available in ductile iron, galvanized steel and polyamide, depending on the channel family. Load classifications vary from lighter residential applications to D400 and E600 installations.
Mesh and Longitudinal Grates
Mesh grates use a grid-based opening pattern and are available in different mesh dimensions. Depending on the product, they may be manufactured from galvanized steel or stainless steel and supplied in 50 cm or 100 cm lengths.
Longitudinal-bar and longitudinal-profile grates create openings that run in the direction of the channel. Stainless-steel versions provide a clean architectural finish, while ductile-iron options are available for higher load requirements.
Decorative Grate Patterns
ANRIN also offers decorative designs named WIRE, CIRCLE, CELTIC and FLORA. These products allow drainage channels to contribute to the visual design of courtyards, pedestrian areas and landscaped spaces.
WIRE and CIRCLE grates are available in coated ductile iron, while CELTIC and FLORA products use uncoated ductile iron. The available load classes vary by design, including C250 and D400 options.
Materials Available for ANRIN Grates
ANRIN grates are produced from ductile iron, galvanized steel, stainless steel, polypropylene, polyamide and aluminium. Material selection should reflect traffic conditions, corrosion exposure, appearance and cleaning requirements.
Ductile iron is commonly used where higher load capacity is required. Galvanized steel is found in slotted and mesh designs, while stainless steel suits projects where appearance and resistance to environmental exposure are priorities. Polyamide grates provide lighter options for residential and pedestrian applications.
ANRIN states that its channels and grates are designed using materials suitable for different operating conditions. The company also offers grate textures with slip-resistance classifications reaching up to R13 for specific products.
How to Select the Right ANRIN Grate
Begin by confirming the nominal width and channel family. A 150 mm grate, for example, cannot automatically be assumed to fit every 150 mm drainage product. Compatibility should always be checked against the relevant technical information.
Next, determine the required load class. A15 products are generally associated with lighter pedestrian use, while higher classes such as D400, E600 and F900 are intended for increasingly demanding traffic conditions. The final selection should also consider water intake, slip resistance, wheel traffic, surrounding paving and preferred appearance.
Conclusion
ANRIN grates are available in several sizes, including 100 mm, 150 mm, 200 mm and 300 mm nominal widths, with common lengths of 50 cm and 100 cm. The design range covers OvalGrip, HEELGUARD, mesh, longitudinal, perforated, slotted and decorative patterns.
Selecting the right grate requires more than choosing an attractive surface. Channel compatibility, water volume, material, load class and site conditions must all be reviewed. Consulting the relevant product data before installation helps ensure that the selected grate performs correctly within the complete drainage system.
