Aluminum 5 inch K Gutter Forming Machine – Fast & Seamless

If you work in residential roofing or light commercial cladding, you’ve almost certainly heard of the Aluminum 5 inch K gutter forming machine. It’s the quiet backbone behind countless tidy soffit lines and rain-tight eaves. I’ve watched crews argue shingle colors for hours, then nod in relief when the gutter run feeds out perfectly formed. Priorities, right?

Market trend, in a nutshell: K-style gutters still dominate North American homes, and 5-inch aluminum remains the go-to for cost-to-performance. Contractors want consistent profiles, fewer callbacks, and machines that don’t chew through coils. To be honest, that last bit is huge—coil scrap eats margins. The model here is built in SHIBAWUXING VILLAGE BO TOWN, CANGZHOU CITY, HEBEI PROVINCE, and it leans into reliability over gimmicks. Surprisingly refreshing.

Key specs (real-world values may vary)

Profile	5-inch K-style gutter; customized gutter available
Material	Aluminum 3003-H14 / 3105-H24 (ASTM B209 compliant)
Thickness range	≈0.45–0.81 mm (0.018–0.032 in)
Line speed	10–18 m/min under typical conditions
Drive & power	Chain or gearbox drive; ≈7.5–11 kW total
Dimensional tolerance	±0.5 mm across flange width (typical, after setup)
Finish compatibility	Pre-painted coils meeting AAMA 2604/2605

How it runs: process flow

• Coil loading (1–2 ton decoiler) → manual/auto threading
• Entry leveling and edge guiding to reduce camber
• Roll-forming through ≈12–16 stations; hardened rollers
• Hydraulic shear synchronized to encoder (clean, burr-minimized cuts)
• Optional bead stiffening/hem forming for rigidity
• Stacking, labeling, wrap, and pallet prep

QC and testing: salt-spray to 1,000 h on coated panels (ASTM B117), coating adhesion cross-hatch, width/height checks at start-up and every 50 pieces, and random leak mock-ups with 3 m water column. Service life? Around 20–30 years in typical suburban exposure with compliant coatings and proper installation.

Where it fits

Residential re-roof, tract homes, small retail strips, and property maintenance. Many customers say the compact footprint makes sense for tight shops; others run it on a trailer for on-site jobs—less handling, fewer dents.

Vendor snapshot (indicative)

Vendor	Strengths	Notes
LW Roll Forming (Cangzhou)	Solid roller hardness; clean shear; customization	Good parts availability; practical pricing
Vendor A	Portable rigs; fast switchover	May trade speed for thickness range
Vendor B	High automation options	Higher capex; strong for large shops

Comparison based on field visits and public specs; real-world use may vary.

Customization

Profile tweaks (lip depth, back flange), bead options, polyurethane rollers for delicate coatings, servo cut-to-length, and branded emboss. The Aluminum 5 inch K gutter forming machine also supports coil widths optimized to your supplier’s stock—saves scrap, quietly boosts margins.

Field notes and cases

• Midwest roofer ran 0.027 in 3105 prepaint at 14 m/min; startup scrap dropped ≈18% after guide tweaks. Crew said “less baby-sitting.”
• Coastal HOA project: AAMA 2604 finish, 1,000 h salt-spray passed; after six months, zero blistering, tidy miters. Installer liked the square cut quality—less filing.

Standards, certifications, and QA

Materials to ASTM B209; coatings aligned with AAMA 2604/2605; salt-spray per ASTM B117. Typical factory QA under ISO 9001 systems. Install practices follow NRCA gutter guidance. It sounds dry, but this paperwork saves headaches—especially on big-ticket bids.

Why pick it

• Consistent profile geometry, fewer leaks at seams
• Friendly on pre-painted coils—less scuffing
• Customization without long lead times
• Backed by a vendor that knows parts and service
