Grille & Angle Selection

Please use the facility above to view the alternatives offered for finishing to our TRENCH HEATER UNITS.

As with all aspects of our manufacturing we cater for bespoke manufacturing.

The following is a list of our most popular grilles: Please let us know your requirements and we will do whatever we can to help.

Please note that unless otherwise detailed our quotations will be for NATURAL SATIN ANODISED ALUMINIUM GRILLE and ANGLE.

All other variations from this are available at an ADDITIONAL cost.

ALUMINIUM, STAINLESS STEEL and POWDER COATED grilles are 6 mm wide x 22 mm deep with a free area of 50%.

HARDWOOD grilles are 10 mm wide x 22 mm deep with a free area of 50%.

NEW FORM STAINLESS STEEL grilles are 10 mm wide x 16 mm deep with a free area of 50%.

Free area space can be altered by changing the spacer sizes between the grille.

CAST IRON grille widths are 155 mm (overall trench unit width 163 mm) and 270 mm (overall trench unit width 278 mm) and maximum lengths of 1550 mm and can be cut to shorter lengths to suit bespoke requirements.

CAST IRON grille sit “seamlessly” into our trench retaining angle sitting on a neoprene rubber pad to improve performance. CAST IRON grille come “fine cast” and can be finished with a zinc rich undercoat with any standard RAL POWDER COATED colours finish.

Due to the much better lateral strength of rigid grille, these are now preferred to the roll up variety in most situations. Rigid grille must be used when tables or chairs will be located nearby. The rigid grille is also recommended for heavier commercial applications.

Both CROSS BLADE and LINEAR grille options are available.

Grille can be manufactured to any size/specification. We also supply grille/gratings to domestic and commercial projects unrelated to trench heating.

BESPOKE grille are manufactured in standard square and rectangular formats in sizes configured to the building aperture or duct size. We use the same materials: NATURAL SATIN ANODISED ALUMINIUM, BRONZE SATIN ANODISED ALUMINIUM, HARDWOOD, NEW FORM STAINLESS STEEL, SOLID STAINLESS STEEL and CAST IRON, as we use on our TRENCH HEATER UNITS.

The high quality and robust nature of our range makes it suitable for domestic, commercial and industrial application.
