*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.
