ASDO TIE BAR DESIGN CAPACITIES
ASDO tie bars can be supplied in two grades of carbon steel and stainless steel. All components are designed to exceed the capacity of the bar.
Table 1 – ASDO-S grades
Minimum elongation for all grades 17%; Minimum charpy for all grades 27J @ -20 °C; ASDO350-S M140-M160 differ from above, refer brochure to table 3 for design resistance
*ASDO540-S bars M105-M160 are quench and tempered and should not be galvanised
ASDO-S systems can be supplied self colour or galvanised as standard. Sizes up to M42 are supplied with forks, pins, turnbuckles, couplers and thread-cover sleeves hot dip galvanized as standard. Note ASDO540-S bars M105-M160 are quench and tempered steel and therefore should not be galvanised.
Bar threads can be formed after galvanising or are re-machined to size following galvanizing; repairs to the zinc coating are made in accordance with DIN EN ISO 1461. Spanner flats on the tie-rods are pressed following hot galvanizing to prevent brittle fracture. Note, due to the nature of the galvanising process the visual finish of galvanised product is variable. If a high level of aesthetic finish is required systems should be subsequently painted after a suitable primer has been applied. ASDO tie bars cannot be supplied with ‘top-coat’ finishes, this should be applied by the customer. Please advise us before placing an order if bars are intended to be painted.
