Wave Plate
- The most popular connector plate.
- Offers the highest performance levels in side-by-side comparison tests with all other competitive products.
- Can be rolled or hydraulically pressed.
- Uses Grade 40 steel – a higher grade than previous plates – so it provides superior plate values.
- Alpine spent more than one and a half years researching, developing and testing the Wave Plate before its introduction.

“H” High-Strength 20 Gauge Plate
- The “H” High-Strength 20 Gauge Plate delivers increased tension values for use in splice joints and other high-stress connections.
- Uses Grade 60 steel, a grade that is stronger than the steel used for the Wave Plate.
- Tooth length matches the tooth length of the Wave Plate, which is important for roller press compatibility in truss production.
- The “H” High-Strength 20 Gauge Plate was previously known as the “HS” Plate.

Hinge Plate
- The 18 gauge Hinge Plate, primarily utilized in the manufactured housing industry, uses Grade 40 steel for superior tension and compression values.
- When used on the top chord of the truss, the Hinge Plate permits the chord to be folded down for transportation and then raised in place onsite.
- Can also be used to eliminate the need for piggyback trusses.
- In side-by-side comparisons, the Hinge Plate meets or exceeds the compression values of competitive products.
