Not sure what to pay attention at when choosing a linear drain? In the following article we will try to briefly describe the construction of the linear drain and what elements decide on a good quality product.
There are many types of linear drains and new solutions are constantly being created to meet the clients' requirements. Despite this, most drains consist of several basic elements.
Most high-quality exclusive drains are made of stainless steel. Most often it is a AISI 304 steel, and in the case of very aggressive environments (e.g. coastal showers) a drain made of AISIC 316 steel can be ordered. Other, less resistant steel types should be avoided because they do not guarantee adequate corrosion and detergent resistance. Another extremely important value is the thickness of the steel used. The cheapest drains are often made of steel, whose actual thickness often does not exceed a millimeter. This causes deformations, not keeping dimensions and low load resistance. It is also worth paying attention to the way the edges and joints are finished. Grinded and rounded edges and joints testify to the high quality of production and attention to detail.
The basic element of each drain is the channel. A rectangular piece of steel that is designed to collect water and drain it into a siphon. The basic difference between individual drain models is the height and width of the channel. Very narrow drains will offer less efficient collection of water than those the optimal width (about 50 - 85 mm). The right height / depth of the channel is equally important and should not be below about 10 mm. In addition to size, the quality and tightness of connections also matter. It is worth paying attention to whether the welds were correctly made and finished. It is best if they form an almost uniform surface with the rest of the joined elements.
Another important element is the flange around the drainage channel. It's presence is necessary for proper installation and sealing of the drain. It is best if it forms a consistent whole together with the channel as in the case of Wiper drains. For convenience and correct sealing, the width of the flange should oscillate within a minimum of 10 mm.
The siphon is another important element of any drain. The number of siphon models offered is huge. They differ due to the size, flow rate, height and watersealing mechanism. However, the main difference is whether the siphon is an integral part of the drain (in the case of Wiper drains these are Slim versions) or is detachable. Most often, integrated siphons offer a smaller height and are made of the same material as the drain itself. However, this prevents the siphon from rotating against the drain. In the case of plastic siphons, be careful of the material they are made of. Only the polypropylene siphons are safe for use in the floor.
Probably the most important factor in terms of appearance and functionality is the drain grating. The material from which it is made and attention to detail in the finish is of great importance for final quality. The grating must be resistant to weight, detergents and high temperature. All edges should be sanded, so that standing on the grille or removing it for cleaning does not risk cutting oneself up with a sharp edge.
But, drain itself is not everything you will need. Therefore, when looking for a drain, pay attention for offered accessories (such as adjusting legs, sealing cuff or key to lift the grate as in the case of our sets). These are not just some nice additions, but often elements necessary for proper installation and sealing of the drain.
