O’Dwyer Steel was established in the early 1950’s in the village of Dundrum, Co. Tipperary by local businessman John J O’Dwyer. John J identified the opportunity to pioneer a steel fabrication business, its principal objective to meet a growing demand for the supply and erection of steel buildings in the agricultural sector.

In the early 1960’s the company began trading as O’Dwyer Steel Co. Ltd and continued to break new ground with the expansion into the commercial and industrial sectors. John J O’Dwyer and his family maintained their association with the business until the 1990’s, by which time the company was the leading supplier of farm buildings in the Munster region.

On July 27th 2000 the O’Dwyer family accepted an ownership buyout of the business from the current Company Board of Directors Sean Dalton, Matt Ryan and John Hanly. The new management structure recognised that the O’Dwyer Steel brand was perceived as a primarily agricultural building enterprise. With this admission came a large capital investment plan and a clear intention to focus efforts on progression of the commercial, industrial and retail divisions.

Following the implementation of this strategic programme O’Dwyer Steel grew into a key player in the construction industry in Ireland. Hit by recession in 2008 and the downfall of the construction sector, the company took the opportunity to refocus and engaged in a large restructuring process which involved the addition of Richard Walsh to the O’Dwyer Steel Board of Directors. As a result of this process the company enjoyed significant growth, built on the strength of its long history, established reputation, experienced gained and successful business relationships.

Following the successful delivery of a large number of projects O’Dwyer Steel is quickly becoming the sub-contractor of choice for a growing number of construction companies across Ireland and abroad each year. This continued growth has been supported by the company’s willingness to diversify.

O dwyer steel workshop Shot-blasting facilities comprise of a semi-automated 4 turbine pre-fabrication Gietart shot-blaster which can accommodate steel sections up to 1500mm wide and 1200mm high and cleans steel to Swedish standard SA 25.

Cutting & Drilling

cutting&drilling Once the material has been through the shot-blasting stage it is transferred to our cutting and drilling facility which comprise of two Ficep semi-automated three spindle saw and drilling lines. The CNC machine part cut lengths and drilling parameters are controlled directly from data files loaded from our detailing office.

Paint Facility

paintingShop In the paint shop, a post fabrication primer is applied to finished components. Shotblasted steelwork is primed with a standard high-build zinc phosphate primer and is applied to a minimum of 75dft on all components. Several types of coatings and colors can be applied to steel if specified by clients. We also offer clients the option to have all steelwork hot-dipped galvanized.


fabrication We operate with an experienced and fully qualified team on fabricators, machine operators and coded welders. All parts are tack-welded and go through quality control procedures including X-ray of welds. Fabricated parts are then passed to our coded welders before welding is completed; welding is always carried out to our engineer’s details.
