Ocean International Technology Co., Ltd

Ocean International Technology Co., Ltd is a China-based supplier listing 18 active products concentrated in the door hardware, access control and low-voltage security equipment segment. The catalogue is anchored in electromechanical locking devices, including 12V/DC single-cylinder electronic rim locks, double-head electronic rim locks, double-wire electric drop bolt locks, and magnetic locks rated at 60 kg (132 lbs), 180 kg double-leaf, 280 kg (600 lbs) LED-indicator, and 280 kg flush-mount variants. Most locking items fall under HS code 8301.40 (locks of base metal), with one exit button under HS 8531.80 (electric sound or visual signalling apparatus, such as push-buttons) and a door closer under HS 8302.41 (base-metal mountings for buildings). The supplier's range extends beyond locks into power and signalling components, biometric terminals, turnstiles and door closers, giving a buyer a single catalogue for the mechanical and electronic sides of a door assembly.

The product mix reflects the practical building blocks used in commercial and multi-tenant access systems: zinc alloy and ABS housings for rim and magnetic locks, iron housings with copper coils for higher-holding magnetic locks, polycarbonate for the fingerprint glass door lock, and aluminum alloy for the door closer sized for 45-65 kg doors. Access control switching power supplies, fingerprint attendance and access control machines, a metal standalone access control unit, a tripod turnstile and a surface-mounted exit button round out the 18-line catalogue, covering both the locking hardware and the control-side electronics that operate it.

The catalogue divides cleanly into three functional groups. The first is rim and drop-bolt locks under HS 8301.40, where the single-cylinder 12V/DC rim lock, the double-head 12V rim lock, and the double-wire electric drop bolt lock share a zinc alloy housing with steel deadbolt or bolt components, the construction most Chinese OEM factories use for fail-secure or fail-safe access doors. The second group is electromagnetic locks, again under HS 8301.40, spanning 60 kg single-door mini magnets up to 280 kg (600 lbs) LED and flush-mount units, with housings in zinc alloy or iron, copper coils, and aluminum or steel armature plates; holding-force ratings in this segment are conventionally expressed in pounds or kilograms and buyers usually see 280 kg (600 lbs), 350 kg (800 lbs) and 500 kg (1,200 lbs) as the standard tiers. The third group covers access control peripherals: a fingerprint glass door lock in polycarbonate under HS 8301.40, a surface-mounted exit button under HS 8531.80, biometric and metal standalone access controllers, a tripod turnstile, and a door closer for 45-65 kg doors under HS 8302.41 in aluminum alloy with steel internals.

Buyers sourcing this category typically evaluate locks on voltage (12V DC or 24V DC are the two operating standards), current draw, holding force for magnets, cycle count for bolts, and housing material. Zinc alloy is the standard for indoor rim locks and small magnets, while iron housings with copper coils are used where higher holding force and heat dissipation are required. ABS and polycarbonate appear on biometric and signalling devices where electrical insulation and a lighter enclosure matter. In the wider category, electromagnetic locks are commonly graded by ANSI/BHMA A156.23 or equivalent regional standards, rim locks and deadbolts by EN 12209 for European projects or UL 1034 for North American access-control listings, and exit buttons by relevant electrical safety norms; CE marking under the EU Low Voltage and EMC Directives, FCC for the US, and RoHS for restricted substances are the certifications most often requested on this product family.
