Import Big F G Lock - Without Lid - 25 Mm — Buy in wholesale FOB from Supplier in Brazil

Sulfibra manufactures the BIG F G Lock without lid in a 25 mm shackle specification, offered in two material grades: AISI 304 stainless steel for corrosive environments, and SAE 1020 galvanized carbon steel for general outdoor use. The padlock body dimensions are 125 mm by 330 mm, with the 25 mm shackle diameter indicating a heavy-duty industrial application range. The carbon steel variant is priced at USD 13.00 ex-works, while the stainless steel variant is USD 20.00 ex-works, though these figures require confirmation with Sulfibra as market prices fluctuate.

AISI 304 stainless steel contains 18-20% chromium and 8-10.5% nickel, providing resistance to atmospheric corrosion and many industrial chemicals, with a typical Rockwell B hardness of 70-90 HRB in the annealed condition. SAE 1020 is a low-carbon steel with 0.18-0.23% carbon content, suitable for galvanizing with zinc coatings typically 50-85 micrometres thick for outdoor durability. The 125 mm by 330 mm body suggests this is a container or gate-class padlock rather than a standard commercial locker lock, with the shackle diameter of 25 mm resisting cutting with standard bolt cutters. The absence of a lid indicates exposure of the keyway to environmental ingress, so buyers in marine or dusty environments should consider shrouded or protected alternatives.

Primary applications include shipping container security, warehouse gate locking, perimeter fencing, and industrial equipment protection where visible deterrence and physical resistance are priorities. The two-tier pricing structure allows buyers to match material specification to actual exposure conditions rather than defaulting to stainless steel. Brazilian manufacturing from the Santa Catarina state location offers potential Mercosur trade advantages for South American buyers. Sulfibra lists no minimum order quantity, lead time, or certification data, so importers must confirm commercial terms, whether ex-works pricing from Iomere includes export packaging, and whether the product carries ABNT or international certification for security hardware.

Sulfibra is located at Rua Ademar Mendes, 130, Iomere, Santa Catarina, 89558-000, Brazil. The supplier holds a Harbour trust tier with zero percent response rate and no recorded average response time, indicating minimal platform engagement history. The address is in a rural municipality in the Santa Catarina interior, suggesting manufacturing or warehousing operations rather than a metropolitan trading office.

The listing provides no information about company founding date, employee count, production capacity, revenue, client references, or quality certifications such as ISO 9001. Sulfibra does not state whether it is the original manufacturer or a distributor of the BIG F G Lock line. Buyers should verify the company's production capabilities, whether it holds ABNT NBR certification for padlock security grades, and whether it can provide material test certificates for the AISI 304 and SAE 1020 grades claimed.
