High strength stainless steel tie bar system with high specification cast forks.
Our SSBS-520 stainless steel tie bar system is manufactured with characteristic yield strengths of 520 N/mm≤. Grade 520 bars with 316 stainless steel corrosion properties.
Our range of stainless steel structural tie bars can be supplied from M12 to M56 sizes, typically we supply M12, M16, M20 and M24.
The tie bars are set to their nominal pin-to-pin length and are supplied pre-assembled which means they are ready to be incorporated into the structure saving valuable time on site.
Stainless steel is corrosion resistant. However it is not completely maintenance-free in all environments. For example in coastal, swimming pool and leisure environments stainless steel requires cleaning with a proprietary cleaner to remove light surface corrosion. The time interval between cleaning will be determined by the severity of the exposure.
The DST520 stainless steel system should only be used in a chlorine environment after full consideration of the associated risks of stress corrosion cracking.
Where stainless steel fittings are in contact with carbon steel bi-metallic corrosion may take place under certain conditions. To prevent this isolation coatings and washers can be supplied for the pins at request.
