Marine Steel & Metals Supply — Corrosion-Ready for Ports, Marinas & Waterfront Infrastructure

Marine Sector Metals Supply by Acier Lachine

Salt, splash, wind, and tight tide windows demand materials and logistics you can trust. Acier Lachine supports marine contractors, port authorities, and fabricators with:

• Corrosion-smart supply: materials and finishes selected for splash/tidal zones, with hot-dip galvanizing and coating coordination timed to install windows.

• On-spec assurance: heat numbers preserved through fulfillment; MTR packages available on request.

• Marine-aware logistics: wharf/ferry/barge coordination, curbside restrictions, night/weekend drops aligned to crane tides.

• Kitting that speeds install: bundles labeled by dock/berth, pier segment, or drawing for faster field assembly.

• Fab-friendly processing: cut-to-size, drilling/punching (where applicable), forming/bending (if applicable), and clean paperwork for submittals and close-out.

Marine Project Types We Support

Typical scopes and how we add value:

• Piers, Wharves & Jetty Works
  W-beams, channels, angles, plate caps, walers, tie-rod hardware (via partners); galvanizing/coatings coordination for long-term exposure.

• Ferry & Cruise Terminals
  HSS frames, platforms, access stairs/guardrails, bar grating and checker plate for walkways; kitting by pier/berth.

• Marinas & Floating Docks
  Aluminum angles/channels/plate, stainless hardware metals, bollard/sleeve pipe; corrosion-resistant selections for brackish/salt.

• Bulk & Liquid Terminals
  Structural supports, pipe racks, dunnage frames, bollards; documentation and labeling for security-restricted sites.

• Shoreline Protection & Access
  Ladder assemblies, catwalks, handrails, sign structures, gangway components; serrated grating for slip resistance.

• Maintenance & Repair Programs
  Replacement plate, treads, brackets, cleat bases; just-in-time drops for limited tide/crane windows.

Steel and Metal Products for Marine Projects

Stocked locally and sourced as required for submittals. (Grades/specs below are examples; availability varies.)

• Structural Shapes
  W-beams, channels, angles for caps, walers, and frames. Typical grades: CSA G40.21 44W/50W (or equivalents).

• HSS / Tubing
  Square, rectangular, round HSS for frames, catwalks, and fender backups. Typical specs: CSA G40.21 / ASTM A500.

• Plate & Sheet
  HR plate for caps, gussets, bearing and base plates; checker/tread plate for decks and stairs. Examples: CSA G40.21 / ASTM A36.
  *Marine/ship plate (e.g., AH36) available on request via sourcing partners with MTRs.

• Pipe & Mechanical Tube
  Bollards, sleeves, piles (fabricated by your contractor), guard posts. Examples: ASTM A53 / A500. (Line/pressure grades on request.)

• Aluminum
  5083/5086 plate and 5052 sheet for docks and gangways; 6061 angles/channels for frames and canopies.

• Stainless Steel
  Sheet/plate/tube for splash/salt exposure and clean areas. Typical alloys: 316/316L (preferred in marine), 304/304L for low-exposure interiors; duplex (2205) on request.

• Grating & Stair Treads
  Bar grating (plain/serrated), checker plate treads and nosings for non-slip access.
