Standards this line is built to
The designations below are cited by the products on this page. A specification is written in these, not in product names, so each one is set out with what it governs. Progress Horizon Trading supplies this line as an authorized distributor across Saudi Arabia.
ANSI/SDI A250.8
The recommended specification for standard steel doors and frames: gauge, construction and grade. Often still called SDI-100.
ANSI/SDI A250.4
The physical endurance test for steel doors and frames: the cycle count behind a door's stated grade.
NFPA 80
Not a test but a compliance standard: how fire doors are installed, inspected and maintained, including the annual inspection and the requirement that every fire door self-closes and positively latches.
UL 10C
The positive pressure fire test for door assemblies. Positive pressure drives hot gas through any gap between door and frame, which makes it the more demanding test and the one North American codes now call for.
ANSI/BHMA A156 series
The American builders hardware standards, each part covering one product family and grading it Grade 1 to 3 by cycle testing.
ASTM A653
Hot-dip zinc-coated (galvanized) steel sheet, with the coating designations that set corrosion life.
SASO standards
The Saudi Standards, Metrology and Quality Organization requirements: what a product must meet to be placed on the Saudi market.
ASTM A240
Chromium and chromium-nickel stainless steel plate, sheet and strip: the grade designations behind 304 and 316.
