CONTINENTAL STEEL Pte Ltd CONTINENTAL STEEL Pte Ltd . The Company . Being one of the biggest premier STEEL suppliers throughout the region, CONTINENTAL STEEL has the .. first fully covered multi-storey warehouse that occupies a floor area of 350,000 sq. ft. The ware- .. house has facilities that allows the following services: .. a) Rust protected storage .. b) Larger stockholding capacity that can accommodate 150,000 tons of material .. c) 24 heavy-duty over-head cranes remotely controlled, some of which are magnetic.

9 D) Ability to service 12 container trucks at any one time .. e) Advanced handling system ensures quick delivery and turn around time .. f) Conducive working environment for more productive workforce in rain or shine .. g) Ability to operate 24hr shifts to meet extra large quantity deadlines.. CONTINENTAL STEEL Pte Ltd is a CIDB registered supplier in the L5 category for all structural STEEL .. Apart from being the supplier of a comprehensive range of quality STEEL sections, CONTINENTAL STEEL aims to extend its commitment to customers by enhancing its services and adding new facilities. A dedicated team is tasked to provide technical support so as to advise the proper usage of STEEL and assist customers in using the PRODUCTS to its best advantage. CONTINENTAL STEEL Pte Ltd 1.. SERVICES.. Technical support Auto Cut and Bend operations With a new team of highly qualified engineers we can advise our customers In current competitive business environment, on the correct use of structural STEEL and efficiency and product specialization are the provide help on the structural design.

10 Essence to a business survival and profitability. So for building contractors and developers, Shearing of STEEL plate material usage control and wastage management plus other fixed overhead investments like Shearing facility that sizes STEEL plates up to machinery and work-shop space should be kept 20mm thickness and maximum width. at a minimum level. To meet this demand we had invested both machinery, skill workers and other infra-structure to provide cut to size and bend to shape reinforcement bars services. Thus removing building contractors and developers tons of on-site work. Our company is also a HDB. approved cut and bend service provider. Powerful hydraulic cutters are being used to cut high tensile reinforcement bars and having capacity to cut bars up to a diameter of 40mm. With auto feeding and measuring mechanism in corporate into the cutter, out-put of the cutting operation could be optimized. Furthermore overhead cranes facilities provide efficiency in both moving reinforcement bars from storage bay to production area and from production area to lorry for timely delivery.
