Ryno’s GRP internal and external corners are compatible with Ryno A Profile GRP roof trims. The pre-formed corners will reduce installation time and labour costs on site as there’s no need for mitring on site. Each corner is available in the same colours for Ryno GRP roof trims. Each GRP trim comes in three standard colours but the trims and corners can be painted in any RAL colour from special order. Contact us on 01752 692 760 for enquiries. Manufactured from glass fibre reinforced polyester, Ryno GRP corners are maintenance free and are impervious to corrosion, rusting or denting.
