Executive Summary and Overview
Practical technical answers regarding shipping container dimensions, site foundation preparation, diesel generator kVA sizing, automatic transfer switches, and nationwide delivery across South Africa.
1. What is the difference between a Standard Container and a High Cube Container?
A standard twenty foot or forty foot ISO shipping container has an external height of 2.59 meters (8 feet 6 inches) and an internal ceiling height of approximately 2.39 meters. A High Cube shipping container provides an additional 30 centimeters (1 foot) of vertical height, measuring 2.89 meters (9 feet 6 inches) externally and approximately 2.69 meters internally. High Cube containers are preferred when stacking tall pallets, installing overhead insulation and lighting for office conversions, or storing bulky agricultural and industrial machinery.
2. What does One Trip Shipping Container mean?
A one trip container is manufactured to strict ISO standards, loaded with clean dry cargo once at the factory port of origin, and shipped into South Africa without undergoing years of repetitive ocean transit. Because it has only completed a single cargo voyage, a one trip unit features clean factory paintwork in dark green or cobalt blue, dent free CorTen steel walls, pristine flooring, and a factory fitted high security lockbox. It offers the longest possible structural lifespan for static storage or architectural conversion.
3. How should I prepare my ground surface before container delivery?
Shipping containers are engineered to bear their entire structural load through their four bottom corner castings. While a full concrete slab or reinforced paving is ideal for permanent installations, a container can also be placed on firm, level compacted gravel or soil supported by four concrete plinths, railway sleepers, or heavy duty paving blocks positioned directly beneath the four corners. Keeping the container level ensures that both cargo doors align properly and open smoothly without twisting the frame.
4. How do I select the right kVA capacity for a diesel generator?
Diesel generators are rated in kilovolt amperes (kVA), where real electrical power in kilowatts (kW) equals the kVA rating multiplied by a power factor of 0.8. For example, a 100 kVA three phase generator delivers 80 kW of usable continuous power. When sizing a generator for a factory, farm, or commercial building, you must calculate both the continuous running load of all equipment and the initial starting surge current required by electric motors, borehole pumps, compressors, and refrigeration condensers. Ideally, a diesel generator should operate between 50 percent and 80 percent of its rated capacity during normal duty.
5. Are your diesel generators tested before dispatch from City Deep?
Yes. Every diesel generator stocked by CONCEPT FROST (PTY) LTD on Rosherville Road, City Deep, Johannesburg South undergoes mechanical inspection and electrical load testing prior to dispatch. Our technicians verify coolant temperature regulation, oil pressure, battery charging alternator output, frequency stability at 50 Hz, and phase voltage balance at 400V three phase or 230V single phase.
6. Can I view the containers and generators in person before ordering?
Yes. Customers, company engineers, and procurement officers are welcome to visit our yard on Rosherville Road, City Deep, Johannesburg South during normal trading hours (Monday to Friday 07:30 to 17:00, Saturday 08:00 to 13:00). Simply call our landline at +27(0) 10 592 0349 or message us on WhatsApp at +27(0) 66 333 3553 so our yard supervisor can have the specific containers or generator models ready for your inspection.
7. How long does delivery take to Cape Town, Durban, or outlying provinces?
Once your order is confirmed and payment is cleared in South African Rand, handling and crane loading take 1 to 2 business days. Transit to Gauteng addresses takes 1 to 2 business days, KwaZulu Natal, Mpumalanga, Limpopo, Free State, and North West take 2 to 4 business days, and Western Cape, Eastern Cape, and Northern Cape take 3 to 5 business days.
8. What payment methods are accepted and how are tax invoices issued?
All orders on conceptfrostcontainers.co.za are priced and settled in South African Rand (ZAR). We accept Electronic Funds Transfer (EFT) and Direct Bank Deposits into our verified corporate bank account, as well as formal Commercial Proforma Invoice orders for corporate procurement teams. Every order automatically generates a SARS compliant Tax Invoice detailing unit serial numbers, VAT breakdown, and physical delivery particulars.
9. What warranty and return protection comes with my order?
Every purchase is backed by our 14 day return and refund policy in accordance with the South African Consumer Protection Act alongside a 24 month structural wind and watertight warranty on one trip containers, a 12 month structural warranty on used cargo worthy containers, and a 12 month or 1000 hour mechanical warranty on new industrial diesel generator sets.
