Crossing between two roof levels: crossover stairs and platforms
One-way vs two-way crossovers, why stock units rarely fit a roof, and how the load reaches the building.
Custom steel catwalk systems: welded steel vs Unistrut
Strut channel or structural steel, floor-supported vs suspended, and the six numbers we need to quote.
Galvanized vs painted steel stairs: which finish for outdoor use
Sacrificial zinc vs barrier coating in freeze-thaw and road salt — cost, lifespan, and where each fails.
Ship's ladder dimensions and angles: the spec guide
The 50–70° pitch band, tread and width dimensions, and how it compares to stairs and fixed ladders.
Roof access: stairs vs. ladders, and what the code allows
Stair, ship's ladder, or a caged ladder to a hatch — how access frequency and code decide.
Work platform vs mezzanine: what's the difference?
One adds a floor, the other serves a machine — and the building code treats them differently.
How to spec a mezzanine before you ask for quotes
Five questions to answer before any fabricator can quote a real number.
Structural mezzanine vs rack-supported platform — when each wins
Engineered structure vs rack-as-frame. Cost, code, and durability tradeoffs.
Mezzanine decking options: bar-grate vs B-deck + concrete vs plate
Why pick mezzanines use bar-grate and storage mezzanines use composite deck.
Grip-strut vs bar-grate: choosing the right industrial tread
Snow shed, tool drop, traction, and durability across the two most common treads.
Warehouse floor-space optimization: cubic vs square footage
When a mezzanine beats a building expansion, and the math behind the decision.
Mezzanine lead times: where the 6 to 8 weeks actually goes
Engineering, fabrication, finish, and install time broken down by week.
Picking a steel fabricator: what to ask before you sign
CWB certification, P.Eng. on staff, install discipline — the questions that matter.
