Ordering stair treads

  1. Select from the tread types shown (T1 to T6).
  2. Refer to Recommended Max. Lengths table in our product guide (page 79). Select a Load Bar Size and Series with a maximum length equal to or greater than the required tread length. For example, if the required tread length is 1100mm, the Series 40 grating with 32 x 5 load bars (A40-325) would be appropriate.
  3. From the Recommended Widths table, choose a width that corresponds to the tread type and Series selected. For example, based on the Series 40 grating and a T1 tread, the tread width would be either 125, 165, 205, 245, 285 or 325mm. Example would be: Tread Type T1 ~ 1100 x 285 from A40 – 325
