International Construction & Certification Standards
Every container and road trailer in Brosan Lojistik’s network complies with rigid international safety, load-securing, and customs security treaties.
Governs external dimensions, corner casting tolerances, and stacking strength. Corten steel corrugated walls resist saltwater corrosion, while interior flooring consists of 28mm weather-resistant treated marine plywood capable of supporting 7,260 kg axle forklift loads.
European structural safety certificate for semi-trailers. Code XL reinforced curtains, front bulkheads (withstanding 50% payload inertia), and reinforced rear doors ensure that form-fit cargo remains secure during emergency braking without extensive internal lashings.
United Nations treaty on the International Carriage of Perishable Foodstuffs. Specifies insulation thermal transfer coefficients (K-values < 0.40 W/m²K) and certifies cooling performance for food, pharmaceuticals, and biological reagents.
Frequently Asked Questions (FAQ)
What is the primary difference between a 40ft GP and a 40ft High Cube (HC)?
The key difference is height. A standard 40ft General Purpose (GP) container has an external height of 8 feet 6 inches (2.591 meters) and an internal height of 2.393 meters, providing 67.7 m³ of volume. A 40ft High Cube (HC) is exactly 1 foot (30 cm) taller at 9 feet 6 inches (2.896 meters) external height and 2.698 meters internal height, yielding 76.4 m³ (an extra 8.7 m³ of volume). High Cube containers are the international standard for lightweight, voluminous freight and high machinery.
What makes a 13.6m Mega Trailer superior for automotive and industrial logistics?
A Mega Trailer offers an internal clear height of 3.00 meters throughout its entire 13.62-meter length (giving 101.3 m³ volume) compared to 2.70 meters in standard trailers (91.2 m³). Mega trailers are Code XL certified, feature hydraulic lifting roofs that raise during loading to allow overhead crane or side forklift access, and can accommodate three stacked Gitterbox automotive cages or 66 double-deck Euro pallets.
How does a refrigerated (Reefer) container maintain temperature?
Reefer containers feature integrated electric refrigeration machinery (typically Carrier Transicold, Thermo King, or Daikin) powered by vessel electricity or portable diesel generator sets (gensets) during road drayage. Air is circulated from the bottom of the container through aluminum T-bar flooring, maintaining precise temperatures from -30°C to +30°C with automated electronic trip data logging.
What is Verified Gross Mass (VGM) under IMO SOLAS?
Under the International Maritime Organization (IMO) SOLAS convention, every packed export container must have its Verified Gross Mass (VGM) certified before loading onto a vessel. VGM consists of the total cargo weight, dunnage/lashing materials, plus the container tare weight. Certified weighbridge scales at Turkish ports (such as Ambarlı, Gemlik, Aliağa, and Mersin) record VGM electronically for shipping lines.
Can a 20ft container carry more weight than a 40ft container?
Yes, in terms of maximum structural payload capacity. A 20ft container has a tare weight of only ~2,230 kg and a max cargo payload of ~28,250 kg. A 40ft container has a higher tare weight (~3,740 kg) and a max cargo payload of ~26,740 kg. Consequently, dense heavy commodities (steel, granite, marble, chemicals) are almost always stuffed into 20ft containers rather than 40ft containers.
