for example, may be sufficient for inner city shopping centres or general building units, but it is not recommended as a long-lasting solution for corrosive environments. Carbon v stainless steel Contractors are more than often under pressure to meet strict project budgets and work to tight schedules. It is therefore understandable that they might need to make savings in some areas, particularly given that stainless steel fasteners roughly cost four times as much as carbon equivalents. We sometimes find that contractors budget only for carbon fixings, and do not consider the impact of weather and corrosion in their decision-making process, but rushing this to meet time constraints may result in important specifications being missed at tender stage. Stainless steel is much more durable than carbon, and can ensure the overall stability of a structure is maintained over time. Because carbon is so much cheaper than stainless steel, it may seem tempting to order it, but the long-term impact of cutting corners on the quality of a structure’s fixings can be damaging. If carbon fixings are the only viable option, using them with moulded plastic heads can improve their life expectancy as the nylon protects the head of the carbon steel fastener. It is also worth noting, however, that 25-year warranties do not apply for carbon fixings, even in low corrosive areas.
