Trench Heating

Sill Line Trench Heating Grille

At Sill Line we have invested considerable time effort and engineering design into our trench heating grille. Where other manufacturers choose to save costs and provide an inferior product our standard grille has a number of design benefits which provide a longer life expectancy. For us as manufactures it is not just about having pride in what we produce, but by using our method of manufacture we can produce a grille that is fit and forget. It will not warp after the heating is used for the first time and require costly adjustments. It provides a much stronger surface and crucially it will last significantly longer. We are often asked to quote for replacement grilles to rival manufacturers trench heating, where an inferior product has warped or bent under loading leaving an unsightly mess. The short term saving from a cheaper grille actually turns into a long term cost. We have a dozen enquires a year to replace damaged grilles from other manufacturers whereas our own grille is still going strong after 30 years and more on site. See below for yourself.
