DioMet Fabrications Ltd offers a diverse selection of customizable steel staircases, providing options for both DIY enthusiasts and professional installation.

Our standard external steel staircases feature a robust hot-dip galvanized finish, ensuring durability, low maintenence and great weather resistance.
