TRUFAST Galvalume Metal Seam Plates for Membrane Attachment
TRUFAST Galvalume Metal Seam Plates mechanically attach single-ply and modified bituminous roof membranes to the substrate. The circular design with reinforcing ribs resists wind uplift, and Galvalume-coated steel provides excellent corrosion protection meeting ASTM D 6294, FM 4470 and DIN 50018. Offered in 2 in. and 3 in. plates in boxes or buckets.
Key Features:
- Circular ribbed design: The plate's circular design and reinforcing ribs provide exceptional strength against wind uplift forces.
- Galvalume coated steel: Made of Galvalume coated steel for excellent corrosion protection.
- Standards compliant: Meets the requirements of ASTM D 6294, FM 4470 and DIN 50018.
- Two diameter options: Available in 2 in. and 3 in. diameters.
- Bulk packaging: Sold in 100-count boxes or 1000-count buckets.
- Membrane attachment: Used to mechanically attach single-ply and modified bitumen membranes to the substrate.

Coverage & How Much You Need:
Plate count per square depends on fastener spacing in the membrane laps as called out by the roof system specification; a 1000-count bucket suits large mechanically attached jobs, while 100-count boxes fit repairs and small areas.
Fit and Compatibility:
Used with appropriate fasteners to mechanically attach single-ply and modified bituminous membranes to the substrate. Fasteners are sold separately; choose plate diameter per the system specification.
Frequently Asked Questions (FAQ):
Q: What sizes are available?
A: The line includes 2 in. plates in 100-count boxes and 1000-count buckets, and 3 in. plates in 100-count boxes.
Q: What are seam plates for?
A: They reinforce the fastening line when mechanically attaching single-ply or modified bitumen membranes to the substrate.
Q: What material are they made of?
A: Galvalume coated steel, which provides excellent corrosion protection.
Q: What standards do they meet?
A: They meet ASTM D 6294, FM 4470 and DIN 50018.
Q: Do fasteners come with the plates?
A: No, fasteners are sold separately; select fasteners compatible with your deck type.
Q: Which size should I use?
A: Use the plate diameter and spacing specified in your roof system specification; the 3 in. plate offers a larger bearing area.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Seam plates are the backbone of mechanically fastened membrane systems; the ribbed circular profile spreads pull-through load across the membrane so laps hold in high wind zones. Match plate diameter and fastener spacing to the system's uplift requirements, and step up to the 3 in. plate where the specification calls for greater bearing area. For large re-roofs, the 1000-count bucket saves trips and keeps fastening crews moving.
Plates and fasteners have sharp edges; wear gloves and eye protection when installing and keep fingers clear of the fastening tool.
