FHA Drip Edge Roll Forming Machine – USA Supplier

FHA Drip Edge Roll Forming Machine — Technical Specification
 
1. Machine Overview
 
The FHA Drip Edge Roll Forming Machine is a fully automated production line designed to continuously form coil metal into the standard FHA (Federal Housing Administration) drip edge profile used in residential and commercial roofing. The system uncoils, feeds, roll forms, and cuts-to-length in a single continuous pass, producing a consistent, straight, and burr-free drip edge profile ready for packaging or direct shipment.
 
2. Product / Profile Specification
Profile type: FHA Drip Edge (standard T-style / L-style, per FHA/HUD roofing edge metal requirements)

Material: Galvanized steel, Galvalume, or aluminum coil

Material thickness: 0.019" – 0.032" (0.4 – 0.8 mm), adjustable per tooling

Coil width (blank width): Typically 6", 8", or per customer specification

Finished leg dimensions: Standard 1-1/2" x 1-1/2", 2" x 1-1/2", or custom per drawing

Standard length: 8', 10', or 12' cut-to-length (custom lengths available)

Surface finish: Painted, mill finish, or galvanized
 
3. Machine Construction
 
3.1 Frame
Heavy-duty welded steel frame, stress-relieved and precision CNC-machined
Frame thickness: typically 16–20 mm steel plate
Surface treatment: sandblasted and painted (anti-rust primer + finish coat)
 
3.2 Forming Stations
Number of forming stations: 10–16 stations (profile dependent)
Roller material: GCr15 bearing steel, hard chrome plated, precision ground
Roller shaft: 45# forged steel, hard chrome plated
Shaft diameter: 60–75 mm (based on machine size)
Roller station spacing and design engineered to prevent scratching, wrinkling, or bowing of the finished profile

Cutting material: Cr12MoV tool steel, quenched and tempered, HRC58-62
Hydraulic station: 3–4 kW motor, hydraulic pump station with pressure gauge and directional valve
Cut tolerance: ±1 mm
 
3.6 Control System
PLC control system (e.g., Delta, Mitsubishi per customer preference)
Touchscreen HMI for length setting, quantity counting, and speed adjustment
Automatic length counting via encoder
