    Stylish aluminium entrances for modern projects

    Suitable for medium and heavy duty commercial use

    Aluminium entrance doors from GJB lend themselves well to projects that are more contemporary in nature, but a near-limitless amount of panel configurations helps to make each unique. Hundreds of colour options can be powder-coated onto the frame for a long lasting and vibrant result, with the additional choice of either a matt and gloss finish.
