  • Hollow Basket Balusters

Our hollow spindles are available in round or square material and they come pre-powder coated in flat black. The inserts are fastened using set screws or tac welded on the round bars and square balusters. Hollow iron balusters offer excellent value and are a great option for those building on a budget.

Our hollow balusters come in both round material and square material.  Customer can easily cut down the lengths to suit their project needs. Hollow material is very light, supporting easy installation.

Powder Coating Colours

All hollow balusters are already pre-powder coated in Flat Black.  Prices include this in the total amount per spindle.  However, there are other powder coating finishes available which you may request: 

  • Wrinkle Black (a textured black , with a slight sheen)
  • Oil Rub Bronze (gritty finish feel, dark colour)
  • Pewter Vein (light dull grey that is pitted like the planet mars)
  • Gold Vein (gold colour with black speckles in it, looks and feels shinier)
  • Gunmetal (dark grey, smooth)
  • Clear Coat (just a clear coat, makes spindles look rustic underneath. Shows flaws of metal)
  • Semi Gloss Black (a shiny smooth black)
  • Silver Vein (silver colour, smooth shiny with black specks in it
  • Stat Bronze (dark brown colour, smooth, shiny feel)

Additional cost of powder coat varies depending on thickness of bar and colour choice. Add character to your home and choose your very own colour to complement your interior finishes today!
