CASTELLATED (HONEYCOMB) STEEL BEAMS
A castellated beam is made by cutting the web of an H beam in a zig-zag pattern and welding the halves back together, offset, to create a deeper section with hexagonal openings. The result is about 50% deeper and much stiffer for the same weight, so it spans further. Pipes and ducts can pass through the openings, saving ceiling height in car parks, halls and offices.

FREQUENTLY ASKED QUESTIONS
DO YOU CUT AND DRILL TO DRAWINGS?
Yes. Beams and plates are CNC cut and drilled to your shop drawings, numbered and ready to erect.
WHAT IS THE MINIMUM ORDER?
There is no fixed minimum. Small orders can share a container with other cargo; we will advise the most economical shipping option.
HOW IS IT PACKED AND SHIPPED?
Members are numbered, bundled and loaded in 40 ft containers or on flat racks with a packing list and erection drawings. We ship FOB Ningbo or Shanghai, or CIF to your port.
CAN I ORDER COMPONENTS ONLY?
Yes. We supply beams, columns, decking and cladding to contractors and fabricators who build the rest themselves.
WHAT IS THE LEAD TIME?
Most orders ship 35–55 days after drawing approval, depending on tonnage and coating. Urgent projects can be split into phased shipments.
WHAT DO YOU NEED FOR A QUOTE?
Dimensions (length, width, height or number of floors), the site location for wind, snow and seismic loads, the intended use, and your preferred roof and wall materials. A sketch or a photo of a similar building is enough to start.
