FAQs
-
A flat top trailer is a flatbed semi-trailer with a single-level open deck and no sides, roof, or curtains. The unobstructed deck allows freight to be loaded from any direction using a crane or forklift. Flat top trailers are used across construction, mining, agriculture, and heavy transport for machinery, equipment, building materials, and any load too large or irregular for enclosed transport.
-
Midland flat top trailers are built to an aggregate trailer mass (ATM) of up to 55 tonnes. Payload capacity depends on axle configuration — Tandem, Tri Axle, or Quad Axle options are available. Your specific ATM and payload are confirmed at order stage based on your load requirements and road access conditions.
-
Midland flat top trailers are available in deck lengths from 40 to 50 feet (approximately 12.2m to 15.2m). Custom lengths can be engineered to suit specific load or compliance requirements. Deck material options include Hardox or checker plate, with flush or raised coaming available.
-
Flat top trailers carry freight that benefits from an open, unobstructed deck — including construction machinery, agricultural equipment, structural steel, pipe bundles, prefabricated panels, and oversized plant. The open deck allows crane or forklift loading from any angle, making flat tops the standard choice for freight that cannot be loaded through a door.
-
A flat top trailer has a single-level deck at a uniform height. A drop deck trailer has a stepped profile — higher at the gooseneck and lower at the rear — which reduces overall load height to allow taller freight to stay within the 4.3m NHVR height limit. Flat tops suit standard-height freight; drop decks are chosen when load height would otherwise exceed that limit. See our Drop Deck Trailers for a full comparison.
-
A flat top semi trailer is a flat top trailer designed to couple to a prime mover via a fifth wheel (kingpin) connection. Midland flat top semi trailers use either a 50mm or 90mm bolt-in kingpin and are available in tandem, tri axle, and quad axle configurations with spring or airbag suspension.
-
Midland flat top trailers are available in Tandem (tandem axle), Tri Axle, and Quad Axle configurations. Suspension options include spring or airbag. The right configuration depends on your load weight, road access conditions, and any PBS assessment requirements.
-
Flat top trailers are used across construction, mining, agriculture, civil infrastructure, and heavy manufacturing. Common applications include transporting structural steel, precast concrete, plant and machinery, pipe, and oversized freight. Their open deck and versatile loading options make them one of the most widely used trailer types in Australian road freight.
-
Flat top trailers use chain and binder systems, ratchet straps, dunnage, and load bars to secure freight in compliance with the National Heavy Vehicle Regulator’s Load Restraint Guide. The appropriate method depends on freight type, weight, and dimensions. Midland flat top trailers are built with lashing rings or coaming to accommodate a full range of restraint configurations.
-
Yes. Midland builds flat top trailers to order and every trailer is configurable to your requirements. Options include deck length, width, axle configuration, suspension type, floor material (Hardox or checker plate), coaming height, kingpin size (50mm or 90mm), and additional features such as headboards, toolboxes, or specific load restraint points.
