Specification sheets
EN 10025 / ASTM grade tables (S355 yield 355 MPa min; tensile 470–630 MPa), Z100–Z350 coating weights, Charpy options to −40°C, and elevator duty charts with test-method references.
TDS · CAD · MTR pathways · install guides
Specification sheets, installation guides, CAD drawings, and engineering data organized for architects, structural engineers, and elevator consultants detailing steel and vertical-transport assemblies—including compressive strength, fire resistance rating, and coating VOC emissions references where applicable.
3.1/3.2 MTRs as default deliverables
We treat mill certificates, section libraries, and elevator installation guides as project deliverables—not afterthoughts—so bidding teams can defend compressive strength, flexural strength, fire resistance rating, and ride-quality assumptions before steel is cut or shafts are surveyed. Application engineers also offer sample coupon coordination and shaft survey walkthroughs when estimators need a repeatable verification path before purchase orders freeze.

Section profiles, connection typicals, thermal bridging notes at clad interfaces, and elevator shaft fire resistance rating drawings for coordination sets.
Handling, welding prep, galvanizing touch-up (abrasion resistance at edges), VOC emissions letters, and elevator modernization sequencing for field crews.
Coverage by product family
Percentages reflect actively maintained documents for standard grades and commercial elevator platforms as of 2026 library audits. Specialty alloys and custom cab interiors may require engineer-generated supplements that include impact resistance, UV stability of finishes, moisture vapor transmission, air permeability at facade edges, and service life expectancy notes tailored to the project climate. Limits: not every duplex/nickel heat has a public CAD family; custom cab interiors may wait for survey before install guides finalize.
Selection trade-offs · verification paths
Specification writers should cross-check compressive strength assumptions against the governing code edition, then confirm thermal bridging details where coated steels meet insulated cladding. Air permeability and water absorption rate notes appear in coating TDS files when facade consultants ask about edge seal longevity. Elevator packages separately call out fire resistance rating interfaces for landing doors and shaft walls so vertical-transport drawings do not contradict the architectural fire strategy. To verify a grade claim before PO: (1) request a sample MTR for the proposed heat family; (2) confirm Charpy temperature and coating mass against the structural notes; (3) book an application-engineer call or shaft survey for modernization scopes; (4) compare published duty charts (speed/load) to the sealed drawings.
Common bid disputes we document openly: (1) green-certification cost premiums versus code-minimum materials—letters separate mandatory CE/EN evidence from optional LEED-oriented recycled content percentage / embodied carbon claims (premiums often 10–20%); (2) natural stone lobby stairs versus fabricated steel feature stairs—slip resistance coefficient and maintenance access differ even when load bearing capacity is similar; (3) elevator modernization reuse versus full rip-out—reusing rails can cut downtime, yet dimensional stability of aged guides may still force selective replacement after survey; (4) prefabricated stair/shaft modules versus traditional on-site fabrication—prefab shortens install calendars while stick-built keeps late field changes cheaper; (5) domestic Buy America lots versus global specialty heats—lead-time resilience versus 20–40% cost deltas on some alloys. Download packages include these caveats so estimators do not treat every grade as freely substitutable. Selection dimensions we publish without naming competitors: yield/Charpy band, coating mass, MTR type (3.1 vs 3.2), lead-time class, recycled content percentage disclosure, and elevator duty/fire interface completeness.
