Explore our engineered aluminum extrusion products. Manufactured from premium 6000-series alloys, featuring precision thermal breaks, impact-resistant profiles, and advanced surface finishes tailored for OEM architectural and structural applications.
Founded in 1973 in Haverhill, Massachusetts, Coastal Industries, Inc. has evolved into an authoritative primary manufacturer and custom OEM solution provider for high-performance aluminum extrusions, commercial window assemblies, and architectural glazing profiles. Unlike third-party distributors or intermediary assemblers, our vertically integrated plant controls every tier of the manufacturing lifecycle.
Our manufacturing philosophy bridges traditional metallurgical rigor with contemporary computer-numerical-control (CNC) extrusion technology. From precision billet heating and press extrusion to advanced polyamide (PA66) thermal barrier insertion, every profile is fabricated to strict 1/8-inch field metrics and ASTM/AAMA performance thresholds.
When procurement managers specify custom aluminum profiles, eliminating intermediate supply chain friction is paramount. By housing extrusion tooling, CNC milling, thermal break crimping, double-glazing assembly, and quality assurance under one roof at 77 Newark Street, Haverhill, MA, we deliver consistent metallurgical grain control, exact dimensional repeatability, and drastically reduced production lead times.

| Alloy & Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Corrosion Resistance | Primary OEM Application |
|---|---|---|---|---|
| 6063-T5 | 185 MPa | 145 MPa | Excellent | Architectural windows, doors, intricate hollow extrusions, trim profiles. |
| 6063-T6 | 240 MPa | 210 MPa | Excellent | High structural load casement frames, curtain walls, heavy framing. |
| 6061-T6 | 310 MPa | 276 MPa | Very Good | Heavy-duty structural components, industrial framework, marine framing. |
| 6005A-T6 | 270 MPa | 225 MPa | High Marine Grade | Hurricane-rated impact assemblies, high-wind load villa projects. |
As international energy codes tighten and decarbonization mandates accelerate, global commercial procurement strategies for OEM aluminum profiles are undergoing a radical shift toward circular metallurgy, thermal efficiency, and precision digital templating.
Global buyers are mandating aluminum extrusions produced using renewable hydro-electric power and high recycled-content scrap (post-consumer recycled aluminum). Sourcing low-carbon billets drastically reduces embodied carbon in commercial envelope designs without sacrificing structural yield strength.
Traditional pour-and-debridge polyurethane insulation is increasingly supplanted by multi-cavity, fiber-reinforced Polyamide (PA66 GF25) thermal strips paired with aerogel inserts. This architecture yields U-factors below 0.18 BTU/hr·ft²·°F, essential for Passive House and Net-Zero building standards.
Procurement managers are favoring fully machined, CNC-milled extrusion kits over raw length profiles. Pre-punched drain ports, corner-cleat routing, and integrated hardware channels enable plug-and-play assembly on offsite construction floors, slashing job site labor costs by up to 40%.
Architectural aesthetics demand maximal glass surface area, pushing extrusion designers to craft structural profiles with ultra-thin sightlines without compromising wind-load resistance (DP 50 to DP 90 ratings). Through advanced finite element analysis (FEA) and high-tensile 6000-series temper optimization, custom OEM factories can now achieve structural mullions that withstand category 5 hurricane wind pressures while retaining sleek, contemporary profiles.
