EI60 and EI90 describe integrity and insulation performance under fire test conditions. The required rating depends on building use, escape strategy and project specification. Leaf, frame, seals, hinges, lock and installation clearances all contribute to system performance.

EI60 and EI90 Fire-Rated Door Guide
Selecting the right steel door requires security level, usage frequency, climate, dimensions and architectural expectations to be evaluated together. The leaf alone does not determine performance; frame, lock, hinges, finish and installation must operate as one system. Clear opening, finished floor, wall depth, swing direction and destination should be confirmed before production.
Technical details
Technical review covers frame profiles, internal reinforcements, distribution of locking points, cylinder protection and hinge capacity. Exterior doors need a coating selected for sunlight, rain, humidity and temperature variation. Export orders should include protective packaging, loading plan, spare hardware and clear installation documents.
Why technical planning matters
Compare quotations by specification rather than total price alone. Dimensions, hardware, finish scope, delivery terms, warranty and service must be reviewed on the same basis. Approve technical drawings before manufacturing. After installation, verify leaf balance, locking action, seal contact and frame anchoring.
Frequently asked questions
Can steel doors be made to custom sizes?
Yes. Frame and leaf dimensions can be engineered for the clear opening, wall depth and finished floor.
Which finish is suitable outdoors?
Choose an exterior coating rated for the project’s sunlight, humidity and rain exposure.
What is needed for a quotation?
Share door type, dimensions, quantity, lock requirements, destination and target date.
