| 1 | Insulated Single Steel Security Door | Residential entrances, apartments, utility rooms | High security / thermal insulation Steel leaf with reinforced frame, multi-point lock preparation, weather seals | $350–$1,200 | 2–5 years for door assembly; hardware may have separate coverage | Declared steel thickness, hardware specification, corrosion-finish details, test reports where applicable | 3–8 weeks | Confirm dimensional drawings, sample approval, export packaging, replacement-parts policy, and pre-shipment inspection |
| 2 | Commercial Hollow-Metal Single Door | Offices, schools, warehouses, service corridors | Commercial heavy duty Galvanized or cold-rolled steel construction with reinforced hinge and lock areas | $450–$1,500 | 1–5 years, depending on finish and hardware package | Steel gauge or thickness declaration, frame profile, hinge-cycle data, finish specification | 4–10 weeks | Verify production capacity, quality-control checklist, packing method, and documented tolerance limits |
| 3 | Fire-Rated Steel Door Assembly | Commercial buildings, plant rooms, stairwells, service shafts | Fire protection Usually supplied as a tested door-and-frame assembly rather than a door leaf alone | $600–$2,000 | 1–5 years; fire-performance validity depends on approved assembly and installation | Valid fire-test classification such as UL 10C or an applicable EN classification; approved hardware and frame details | 5–12 weeks | Check that certificates cover the exact size, glazing, hardware, frame, and installation configuration being purchased |
| 4 | EN 1627 RC2 Steel Security Door | Homes, apartments, small commercial premises | Moderate forced-entry resistance Designed for resistance against common hand tools under the tested configuration | $800–$2,500 | 2–5 years | Independent EN 1627 classification for the complete door set, including frame, lock, hinges, and glazing if used | 6–12 weeks | Request certificate number, laboratory identity, tested dimensions, and confirmation that supplied components match the test sample |
| 5 | EN 1627 RC3 Steel Security Door | High-value residences, financial rooms, restricted-access facilities | Enhanced forced-entry resistance Higher resistance level than RC2 when the complete tested assembly is correctly installed | $1,200–$4,000 | 2–5 years | Independent EN 1627 / EN 1630 evidence for the complete assembly and installation requirements | 8–16 weeks | Validate the certificate scope, steel construction, locking points, frame anchoring method, and installer requirements |
| 6 | Double Steel Security Door with Panic Hardware | Industrial buildings, public facilities, emergency exits | Wide opening / controlled egress Two-leaf steel assembly with panic or emergency-exit hardware options | $1,000–$3,500 | 1–5 years | Hardware conformity documentation, door-cycle information, fire-rating evidence where required, and clear handing details | 6–14 weeks | Confirm active and inactive leaf operation, shipping protection for hardware, spare-part availability, and site-installation guidance |
| 7 | Louvered Steel Security Door | Generator rooms, plant rooms, electrical rooms, ventilation areas | Security with airflow Reinforced steel frame and louver design; not normally suitable where fire or acoustic isolation is required without additional testing | $500–$1,800 | 1–3 years | Airflow data, louver construction details, corrosion coating specification, and any fire or acoustic test evidence requested | 4–10 weeks | Check louver geometry, drainage, insect-screen options, outdoor coating system, and packaging against deformation |
| 8 | Stainless-Steel Security Door | Coastal properties, food facilities, laboratories, humid environments | Corrosion-resistant construction Common grades include 304; 316 is generally selected for more aggressive chloride environments | $1,000–$4,500 | 2–5 years; corrosion coverage must be stated separately | Material grade certificate, weld-finish specification, salt-spray or corrosion data where relevant, and hardware material details | 6–14 weeks | Request mill certificates, confirm dissimilar-metal compatibility, inspect weld quality, and define cleaning requirements |
| 9 | Ballistic-Resistant Steel Door | Security rooms, critical infrastructure, protected control areas | Ballistic protection Performance depends on tested steel layers, glazing, frame, locks, and the exact ammunition classification | $2,500–$10,000+ | 1–5 years; ballistic performance is tied to the tested configuration | Independent ballistic test report, stated standard and threat level, complete assembly scope, and installation instructions | 10–20 weeks | Never accept a steel-thickness claim as a ballistic rating; verify laboratory documentation and exact tested components |
| 10 | Custom Oversized or Blast-Resistant Steel Door | Industrial plants, infrastructure, transport facilities, specialized enclosures | Engineered project solution Requires project-specific structural, pressure, fire, acoustic, or security engineering | $5,000–$30,000+ | 1–5 years for workmanship and materials; project specifications may override standard terms | Project calculations, independent test reports where required, structural drawings, weld procedures, and approved installation method | 12–30 weeks | Evaluate engineering credentials, reference projects, inspection-and-test plan, milestone approvals, and export documentation |
