Questions about SABdrain? See below answers to frequently asked questions.
SAB is a part of System Group, a group of companies founded in 1979, one of the main European holdings in the supply of piping systems in PE and PP. The company was born in Sirolo (AN) in 2003, and it moved to Sant’Angelo in Vado in 2007. SAB specializes in moulding and extrusion of plastic materials for the production of compression and electrofusion fittings, drainage channels and products for drip irrigation. They are active in three sectors: irrigation, water and gas, and drainage.
SABdrain channels are manufactured & shipped out of Italy. Grates are a mix of overseas & local suppliers.
We hold a large amount of stock in our warehouse, which can be shipped out within a day.
Polypropylene is a material with excellent mechanical, physical and chemical properties.
Some of the most significant properties of polypropylene are:
Chemical Resistance: Diluted bases and acids don’t react readily with polypropylene
Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of deflection (like all materials), but it will also experience plastic deformation early on in the deformation process, so it is generally considered a “tough” material. Toughness is an engineering term which is defined as a material’s ability to deform (plastically, not elastically) without breaking..
Fatigue Resistance: Polypropylene retains its shape after a lot of torsion, bending, and/or flexing.
Insulation: polypropylene has a very high resistance to electricity.
SABdrain channels are sold in 1M lengths to be joined together. They are easily cut, allowing installers to achieve exactly how many metres they need.
Yes, it is extremely important that a grate is inside the channel to prevent bowing when concreting. It is impossible to install a grate if the channel has bowed after concrete has set.
A great tip is to use a temporary grate (like timber) to prevent any concrete getting on the grates.
SAB channels have preset lateral connection for 90 degree joining of 2 channel units together. Allows right angles, corners, tees & crosses without any additional fittings.

Yes we stock a range of Jonite grates that fit into our channels.
Like most metals, cast iron goes through a natural oxidation process, resulting in an outer protective coating known as rust. This process is called Patina.
Patina is a naturally occuring process and shouldnt be confused with corrosive rust. Pantina is good for iron as it provides a protective layer.

The nominal wheel loading refers to the weight of 1 wheel of the vehicle.
For example, if you estimate the heaviest vehicle that will be driving over the drain weighs 2215kg. The nominal wheel loading is 553.7 kg (2215 ÷ 4 = 553.75). Therefore you will require a Class B rated grate (Class B nominal wheel loading is 2670kg).
The load rating of a grate is a specification of the amount of weight the grate can withstand.
Residential- Will withstand 1.5 ton wheel loading. Footpaths & driveways.
Class A – 330kg nominal wheel loading. Pedestrians, cyclists.
Class B – 2,670kg nominal wheel loading. Driveways (cars & light commercial vehicles)
Class C – 5,000kg nominal wheel loading. Areas with slow moving traffic (shopping centres). Heavy commercial vehicles.
Class D – 8,000kg nominal wheel loading. Highways & roads, lightly loaded forklift, warehouse
Class E – 13,700kg nominal wheel loading. Commercial heavy wheeled traffic, hardwheeled forklifts, construction/military/mining vehicles
Class F – 20,000 nominal wheel loading. Docks, wharfs, airport serviceways & taxiways
Class G – 30,000 nominal wheel loading. Extra heavy duty, airport runways, docks

Many different factors including proximity to pool, budget and aesthetics affect which grate can be used. Stainless steel grates are the most popular choice.
