The doorLink 3640 Long Grooved Panel brings carriage house character in a longer panel configuration — the same 26-gauge 3-layer sandwich construction and R-10.25 insulation as the 3630, but with the extended groove profile that creates a broader horizontal appearance on the door face. Pebble grain embossed steel interior backskin, 20-gauge full vertical hinge plates, and twelve color options — including four bi-directional woodtones — make the 3640 one of the most versatile carriage doors DOORTEC installs across the OKC metro.

Hot dipped galvanized steel construction with hemmed inside return rail provides superior strength and durability.
Includes 0.25 mil rust inhibiting primer and 0.75 mil exterior topcoat that resists fading and chalking, while providing consistent color from panel to panel and more durability.
Galvanized steel hinge plates run the full height of each section at all hinge locations to facilitate the attachment of hinges, handles, struts, and step plates.
For superior strength and better sealing against wind, rain, and snow.
Provides added strength while securing replaceable U-type bottom astragal weatherstrip to help keep the elements out.
Sandwich type construction with polystyrene insulation pressure bonded between two sheets of hot dipped galvanized steel enhances your home's energy savings, makes your door operation quieter, and reduces exterior noise in your garage.
Environmentally friendly insulation that will not degrade with vibration or time.
Bi-directional wood grain pattern gives the appearance of traditional wood doors. Available in Oak, Walnut, Driftwood, and Light Cypress woodtone finishes.
The doorLink 3640 shares the same 12-color lineup as the 3630 — eight prefinished pebble grain colors and four bi-directional woodtone finishes. The longer groove profile of the 3640 panel creates a distinctly different visual rhythm with the same color palette. Colors may vary from actual product.
doorLink’s bi-directional wood grain pattern creates an authentic wood appearance in both directions, delivering the look of traditional wood carriage doors with the durability and low maintenance of steel construction.
*Colors may vary from actual product. Physical samples available through DOORTEC — request before finalizing your selection.

The doorLink 3640 Long Grooved Panel takes the same 26-gauge 3-layer sandwich construction and R-10.25 insulation found in the 3630 and applies a longer groove stamp that creates a broader, more horizontal panel appearance. The result is a carriage house door that reads as taller and more architectural on larger openings — particularly effective on 16-foot and wider double-car garages in the OKC metro. Like all 3600-series doorLink models, the 3640 includes 20-gauge full vertical steel hinge plates and a pebble grain embossed steel interior backskin — construction quality that distinguishes the 3600 series from the entry-level 430/431 carriage range. DOORTEC is an authorized doorLink dealer serving Oklahoma City, Edmond, Norman, Moore, Yukon, and Midwest City. Call (405) 720-7107 for a free installation quote.
The 3630 and 3640 are structurally identical — same gauge, same R-value, same colors, same window options, same sizes. The difference is purely visual: the 3630 Short Grooved Panel creates more horizontal lines per section, while the 3640 Long Grooved Panel uses fewer, wider grooves for a cleaner, more modern look. Both carry the full 12-color lineup including four bi-directional woodtones (Oak, Walnut, Driftwood, and Light Cypress) and the same six carriage-style window inserts. DOORTEC carries both models and can show you samples at any of our Oklahoma City locations.
