Dunnage Steel is fabricated structural framing that elevates rooftop or floor-mounted mechanical equipment. In London, The Grate Guys makes dunnage steel to spec: measured, built, and finished for the real conditions.
Most London dunnage steel jobs involve rooftop units, chillers, and mechanical platforms. Elevated structural support for mechanical equipment above decks are the recurring drivers; each London order is sized to its own situation, not a one-size approach.
What drives dunnage steel in London (Middlesex County) is advanced and food manufacturing, healthcare and research, automotive and rail manufacturing, insurance and finance, logistics. Activity clusters in Innovation Park / Wonderland Road corridor, Trafalgar industrial area, Veterans Memorial Parkway employment lands, Sovereign Road / Forest City industrial parks. Much of the demand tracks London's industrial corridors near operations like London Health Sciences Centre and St. Joseph's, Western University, Maple Leaf Foods and food processors, General Dynamics Land Systems (defence), 3M Canada, Hanwha / rail and parts manufacturers — heavy commercial and institutional sites, no two with the same spec.

That local picture shapes how The Grate Guys assesses, equips, and prices each London order.
