STEEL SECURITY
DOOR MANUFACTURER

The appropriate RC rating depends on asset value, location risk, and response time. For residential properties and low-risk commercial storage, RC2 provides adequate protection with 3-minute resistance. Most commercial retail and office applications specify RC3, which resists attacks for 5 minutes using crowbars and drills. High-value facilities including banks, data centers, and jewelry stores typically require RC4, offering 10-minute resistance against power tools. Insurance requirements and local regulations may also mandate specific ratings. Our technical team can help assess your risk profile and recommend appropriate security levels.

Steel security doors are tested according to EN 1627-1630 standards by accredited testing laboratories. EN 1628 tests resistance to static loads such as prying forces. EN 1629 tests dynamic resistance including impact loading. EN 1630 involves manual attack testing where skilled testers attempt to defeat the door using the tool set defined for each resistance class. The door must prevent through-passage and prevent the lock from being operated for the defined time period. Euwoo provides test reports from accredited laboratories documenting the security rating of each door model.

Yes, steel security doors can be manufactured with combined fire and security ratings. These dual-rated doors undergo separate testing for fire resistance (EN 1634-1) and security (EN 1627). The construction must satisfy both requirements, which means careful engineering of seals, glazing if present, and hardware. Fire ratings of 30, 60, and 90 minutes are available depending on the security rating and configuration. Note that not all combinations are possible, particularly at higher fire ratings with vision panels. Contact our engineering team early in the project to confirm available options for your specific requirements.

Steel thickness varies by security rating. RC2 doors typically use 1.2-1.5mm cold-rolled steel for the door leaf skins. RC3 doors increase to 1.5-2.0mm thickness. RC4 doors use 2.0-3.0mm steel with additional hardened steel plates in the lock zone. Frame profiles use similar or heavier gauges. These thicknesses represent the skin material; internal reinforcement adds significant additional steel in critical areas. All steel is galvanized before fabrication for corrosion protection, then powder coated for durability and appearance.

Door weight depends on size, security rating, and options. A standard single RC2 door (900x2100mm) weighs approximately 40-60kg. RC3 doors of similar size weigh 60-90kg. RC4 doors can weigh 90-150kg or more. Adding fire rating, vision panels, or stainless steel cladding increases weight further. Frame weight adds another 30-60kg depending on configuration. Heavy doors require appropriate hinges (typically three or four per leaf) and may require reinforced floor construction and assisted closing devices. We provide exact weights with each quotation.

Maximum dimensions depend on security rating and configuration. For single doors, typical maximums are 1100-1200mm wide and 2400-2500mm tall. Double doors can reach 2400mm combined width. Height over 2400mm requires additional locking points to maintain security. Very large openings may be served by paired doors or door-and-sidelight combinations. Custom sizes are manufactured to order. For openings exceeding these dimensions, contact our engineering team to discuss solutions including sectional security doors or custom assemblies.

Minimum locking points increase with security rating. RC2 requires at least 3-point locking. RC3 typically uses 5-point or 7-point systems. RC4 and above often specify 7-point or 12-point locking. The number of points should match door height, with taller doors requiring more points to prevent prying along the full height. Twelve-point systems that lock on all four edges provide maximum security for vault-level applications. More locking points increase security but also add weight and cost. Our specifications indicate appropriate configurations for each door size and rating.

Yes, steel security doors can be fully integrated with access control systems. Options include electric strikes for fail-secure or fail-safe operation, electromagnetic locks, electric latch pullback on multi-point locks, and motorized locking. Doors can be factory-prepared for card readers, keypads, biometric readers, and intercom systems with appropriate cable routing and mounting reinforcement. We coordinate with access control specifiers to ensure correct preparation. For complex systems, provide access control specifications when ordering so we can engineer appropriate door preparation.

We supply doors with high-security cylinders from major European and Asian manufacturers. Options include standard keyed cylinders, master key systems, construction keying, and restricted keyway cylinders that prevent unauthorized key duplication. Cylinder security class matches the door's RC rating: Class 4 minimum for RC2, Class 5 for RC3, and Class 6 for RC4. For projects requiring specific cylinder brands to match existing key systems, we can accommodate most major brands. Electronic cylinders and smart lock systems are also available for advanced access management.

Minimum order quantities depend on door configuration. Standard specifications with stock finishes have a minimum of 20 units. Custom sizes or special finishes may have minimums of 10-20 units. OEM/ODM programs with private labeling typically require 50+ units. For sample or prototype orders, we can sometimes accommodate smaller quantities with adjusted pricing. Contact our sales team to discuss your specific requirements and volume expectations.

Lead time depends on configuration and order size. Standard configurations ship in 20-30 days from order confirmation. Custom sizes or special finishes add 10-15 days. Large project orders are scheduled based on production capacity and may be delivered in phases. Fire-rated and dual-certified doors may require additional lead time. For urgent requirements, contact us to discuss expedited production options. We recommend ordering 8-12 weeks before required installation date to allow for production, shipping, and any unforeseen delays.

Pricing is based on door size, security rating, finish, and hardware configuration. RC2 doors cost less than RC3, which costs less than RC4, reflecting the increased material and engineering content. Custom sizes, special finishes like stainless steel cladding, and premium hardware add to base pricing. Volume orders receive progressive discounts. We provide detailed quotations itemizing each component. For budget planning, contact us with approximate specifications and quantities for preliminary pricing.

Steel security doors require solid wall construction for proper anchoring. Acceptable materials include concrete (minimum 150mm), solid masonry (minimum 140mm), and reinforced concrete block with grouted cores. Standard steel stud walls with drywall cannot provide adequate anchorage for security-rated frames. If existing construction is lightweight, wall reinforcement or frame-within-frame solutions may be required. Our technical specifications include anchoring requirements for each security rating. Verify wall construction before specifying security doors to avoid installation complications.

Steel security doors require minimal maintenance. Annual inspection should check lock operation, hinge condition, seal integrity, and finish condition. Lubricate lock mechanisms and hinges annually with appropriate lubricant. Clean powder-coated surfaces with mild detergent. Inspect weatherseals and replace if deteriorated. For coastal or industrial environments, check for corrosion at edges and fastener locations. Address paint damage promptly to prevent rust spread. Door closers may require adjustment over time as seals compress. With proper maintenance, steel security doors provide 25-30+ years of service.

Euwoo provides a standard 5-year warranty covering manufacturing defects in materials and workmanship. Hardware components carry manufacturer warranties which may differ. The warranty requires that doors are installed according to our specifications and maintained appropriately. Damage from misuse, improper installation, or environmental factors outside door specifications is not covered. Extended warranty programs are available for project requirements. Warranty claims require original purchase documentation and installation certification.
