CE Approval

CE Marking for all construction products, became mandatory on 1 July 2013. For fabricated structural steelwork, CE Marking became mandatory on 1 July 2014. CE Marking demonstrates compliance with the appropriate manufacturing standard for a product.


Under the Construction Products Regulation new legal obligations have been placed on manufacturers, distributors and importers of construction products used within the EU to CE Mark their products where they are covered by either a harmonised standard or European Technical Assessment (ETA). This applies not only to constituent products (such as steel beams, bolts etc) but also to fabricated elements and systems made from CE Marked products.


Bonnar Engineering Letterkenny Ltd achieved this standard in 2014 and continual assessment of our CE approval is ongoing in order to ensure adherence to the standards required in the future.
