Security doors, gates and bars in Newcastle
Newcastle serves northern KwaZulu-Natal with a mix of face-brick homes in Fernwood, Lennoxton and Pioneer Park, townhouses, and large township areas such as Madadeni and Osizweni. Many older houses still have steel windows with simple trellis doors, and newer builds use aluminium frames. Summers are hot with heavy thunderstorms, while winter frosts and dry air are tougher on paint than rust, though a zinc primer is still worth having. Shops in the town centre order folding gates and steel back doors, and factories in the industrial area need heavy slamlock gates. Fabricators work from the Newcastle industrial area and also serve Dannhauser and Utrecht.

Typical security door locks requests in the area come from:
- Houses: a cylinder lock box on the front gate and the same key on the kitchen and patio gates
- Shops and restaurants: a lock on the shopfront gate and a stronger bolt on the back door
- Factories and warehouses: heavy lock cases on yard gates and store rooms, with a restricted key system
- Townhouses and complexes: keyed alike cylinders for front and patio gates, kept within the complex rules
- Schools, clinics and churches: a master key plan for rooms and classrooms, with fire exits that open from inside
- Farms and smallholdings: heavy lock boxes on workshop and store room doors, with a master key for the farm manager
- Flats and apartments: a neat lock box on the entrance gate with a thumb-turn inside for quick exit
Local tips for Newcastle
Common here: trellis doors and bars for houses, folding gates and steel doors for shops. Ask each installer to allow for this: ask for the bars to be fixed through the brick and not only into plaster. Work usually comes from here: fabricators in the Newcastle industrial area and Madadeni.
Security Door Locks are usually made in steel lock box, brass or nickel cylinder, fits stiles from 25 to 50 mm wide, with slamlock, cylinder, 3-lever or multi-point and plated, powder coated or stainless steel. Locally: hot storms and cold dry winters: paint needs a proper zinc primer.
