We have developed a range of secure ventilation louvres that does not require additional burglar proofing to prevent access. These louvers can be either double or single bent, and can be manufactured in mild steel or stainless steel. Slat thicknesses of 3mm and copious use of fasteners form a very strong structure. Louvres are fitted with insect proofing stainless mesh as standard. Very stringent corrosion specifications are adhered to.
Light versions (with 1.6mm stainless slats) are also available.
