Construction metalwork refers to the metal products and semi-finished goods used in the construction of buildings and structures. This includes everything from structural steel beams and columns to smaller items like brackets, anchors, and railings.
Application
Metal is valued in construction for its strength, durability, and versatility. Construction metalwork covers a broad range of products, each serving a specific purpose on the building site.
Structural metalwork
- Steel beams and columns — Form the skeleton of larger buildings or provide support where wide spans are needed, such as above garage doors or open-plan living areas.
- Lintels — Steel bars or angles placed above window and door openings to carry the weight of the wall above.
- Reinforcement (rebar) — Steel bars embedded in concrete to add tensile strength to foundations, floors, and walls.
Architectural and finishing metalwork
- Railings and balustrades — Provide safety on staircases, balconies, and elevated walkways.
- Window and door frames — Aluminium or steel frames offer slim profiles and long service life.
- Flashings and drip edges — Thin metal strips that prevent water from entering joints in roofs and facades.
Fasteners and connectors
- Brackets and joist hangers — Connect timber or steel members at joints.
- Anchor bolts — Secure structural elements to concrete foundations.
- Screws, nails, and bolts — Everyday fasteners available in various metals and coatings for different environments.
Tips for DIY builders
- Use galvanised or stainless-steel products in exposed or damp locations to prevent rust.
- Always match the metal type to its purpose — structural steel must meet specified grades.
- Wear gloves and eye protection when cutting or grinding metal on site.
- Check local codes for fire-rating requirements when using steel framing.
