Wholesale Steel Security Doors Bulk Buy

Product Overview

- Wholesale steel security doors (armored metal doors and automatic garage door options) designed and manufactured by Shenzhen GP Global for bulk buyers.

- Constructed from high-strength alloy steel with weather-resistant surface treatments; available in standard and customizable sizes (single widths 90–120 cm, double up to 200 cm; heights 205–250 cm; thickness 60–80 mm).

- Offered as both manual and automated solutions (sectional, roller and side-hinged garage doors) with factory quality inspections and full production capacity for large orders.

Product Features

- Robust materials: high-strength alloy steel panels, 2–4 mm core metal plates, and durable coatings (fluorocarbon or zinc‑aluminum) for corrosion resistance.

- Insulation and fire protection: rock wool or ceramic fiber fill for thermal insulation and fire resistance (up to ~120 minutes).

- Sealing and weatherproofing: EPDM gaskets and tight seals to block water, wind, dust and insects.

- Heavy-duty hardware: forged stainless hinges, multi-point anti-pick/anti-drill locks, ergonomic brass/stainless handles, and optional biometric/keyless entry.

- Automation and safety (for garage doors): choice of chain/belt/screw openers, quality tracks and rollers, infrared sensors and safety edges.

Product Value

- Security: high physical resistance to forced entry and advanced locking systems protect people, vehicles and assets.

- Energy and cost savings: insulating core reduces heating/cooling costs and improves comfort.

- Safety and reliability: fire-rated construction, weatherproofing and safety sensors reduce risk and liability.

- Aesthetics and resale: modern finishes and customizable options improve property appearance and value.

- Economies of scale: bulk purchasing lowers per-unit cost and ensures supply continuity for developers, distributors and contractors.

Product Advantages

- Superior protection compared with standard doors due to thicker panels, reinforced cores and multi-point locks.
