Custom Aluminium Flashings and Metal Pressings
We press and weld custom aluminium flashings to your exact specifications. Submissions are processed rapidly at our Dublin facility with nationwide Irish delivery.
Silicone is not a building material. Precision over speed.
Project Profile
Dublin Manufacturing Excellence.
We fabricate B2B components at our Dublin facility. Standard 2mm marine-grade alloy ensures durability in coastal environments. Qualicoat powder coating provides RAL-matched weather protection. Fast nationwide delivery in 3 to 5 working days. All measurements verified through the app are built to a 0mm fabrication tolerance.

Precision Pressed Metalwork and Alloys
Our custom flashings are fabricated from high quality marine grade sheets in thicknesses from one point five millimetres to four millimetres. We use 1050A grade alloy for general pressings to ensure clean bends without cracking. For projects requiring anodised finishes, we supply 5005 J57S grade sheet. We use modern CNC press brakes to achieve precise bend angles. This ensures that every flashing sits flush on the building envelope and aligns with structural drawings.

Weatherproofing Details and Joint Design
Each flashing section is designed with safety folds and drip edges to channel water away from window reveals and wall joints. We TIG weld internal and external corners in house to guarantee a watertight joint. We recommend using a fifty millimetre overlap at joints, sealed with high performance polymer sealant to ensure continuous weatherproofing.

Window Reveal and Opening Seals
Window reveals are high risk zones for water ingress, especially in exposed coastal areas of Ireland. Our window opening flashings seal the junction between the window frame and the external wall structure. This protects the insulation envelope and prevents damp from staining the interior reveals.

Roofline and Parapet Detailing
Our flashing profiles protect roof eaves, valley gutters, and parapet walls. The systems connect with standard roofing membranes and drainage products. We fold apron flashings, valley trays, and step details to order to meet specific architectural requirements.

Qualicoat Powder Coating and Finish Standards
We apply Qualicoat architectural powder coatings in any standard RAL color code. This guarantees UV stability and weather resistance. The finished coatings match other envelope elements like window frames and cladding panels, creating a unified architectural appearance.
Technical FAQ
Frequently Asked Questions
What is the maximum thickness of aluminium sheet you can fold?
We fold aluminium sheet up to four millimetres in thickness on our CNC press brakes.
Can you fold flashings from custom drawings?
Yes, we press flashings to your exact specifications. You can submit CAD files or sketch dimensions through our contact form.
Are your flashings supplied with preformed corners?
Yes, we weld internal and external corner components in our workshop to guarantee watertight installations on site.
What lead times apply to custom flashing orders?
We fabricate and deliver custom flashing orders nationwide within three to five working days.
What alloys do you use for flashings?
We use 1050A grade alloy for standard powder coated flashings. We use 5005 grade alloy for anodised finishes to ensure color consistency.
How do you prevent galvanic corrosion at fixing points?
We recommend using stainless steel fixings equipped with EPDM or neoprene washers to prevent direct contact between the steel fastener and the aluminium sheet.
