Introduction
Choosing the correct fixings for steel buildings in Ireland is essential for safety, durability, and compliance with modern construction standards. Whether you are erecting agricultural sheds, industrial units, warehouses, or commercial steel structures, the fixings used play a critical role in the long-term performance of the building.
At Icon Fasteners & Supplies Ltd, based in Wicklow Town, we supply trade-grade fixings for steel buildings with nationwide delivery across Ireland or local collection from our Wicklow hardware store. This trade guide explains how to select the correct fixings for Irish site conditions and construction requirements.
Why Fixing Selection Is Critical in Steel Construction
Steel buildings rely on fixings to safely transfer loads between sheets, purlins, beams, columns, and foundations. Incorrect fixings can result in:
- Structural weakness or movement
- Premature corrosion
- Fixing failure under load or wind pressure
- Failed site inspections
- Increased maintenance and replacement costs
Given Ireland’s weather conditions — high rainfall, wind exposure, and coastal environments — fixings must be selected carefully to ensure long-term performance.
Key Factors When Choosing Fixings for Steel Buildings
1. Steel Thickness & Application
The first consideration is the thickness of the steel being fixed.
- Light gauge steel (up to 3mm):
Used for roofing sheets, cladding, rails and light framing
→ Requires light section TEK screws - Heavy gauge steel (up to 12mm):
Used for portal frames, columns and structural members
→ Requires heavy section TEK screws or structural bolts
Using fixings outside their intended capacity can cause drill point failure, reduced holding strength and costly delays on site.
2. TEK Screws for Steel Buildings
TEK screws, also known as self-drilling screws, are the most commonly used fixings in steel construction across Ireland. Their ability to drill and fix in one action saves time and labour.
Common TEK screw types include:
- Light section TEK screws
- Heavy section TEK screws
- Stitcher TEK screws (sheet-to-sheet fixing)
- Wing-tip TEK screws (timber to steel)
- Bi-metal TEK screws (high corrosion resistance)
At Icon Fasteners, we stock a full range of TEK screws for agricultural, industrial and commercial steel buildings, all available with fast nationwide delivery across Ireland.
3. Corrosion Resistance for Irish Conditions
Ireland’s damp climate makes corrosion protection one of the most important factors when choosing fixings.
Common finishes include:
- Bright zinc plated: Internal use only
- Galvanised: Suitable for outdoor applications
- Exterior-coated fixings: Enhanced corrosion resistance
- Stainless steel / bi-metal: Coastal or aggressive environments
Using the correct corrosion protection significantly extends the life of the steel building and reduces maintenance costs.
4. Structural Bolts, Nuts & Washers
While TEK screws are suitable for sheeting and secondary steelwork, primary structural connections require bolts and nuts.
Commonly used products include:
- DIN 933 hex bolts
- DIN 934 full nuts
- Structural washers (Form C or DIN washers)
- Threaded bar and anchors
Icon Fasteners & Supplies Ltd stocks a full range of nuts, bolts and washers for steel construction, with consistent availability for large projects.
5. CE Marking & ETA Compliance
Many steel building projects in Ireland require fixings that are CE marked or ETA approved, particularly:
- Commercial developments
- Industrial facilities
- Public sector projects
Certified fixings provide assurance that products meet European performance standards and are suitable for structural use. Selecting compliant fixings early helps avoid delays and failed inspections.
