Here are what we could offer to our customers about large span construction.
Firstly, detail technical sevice and know-how for steel engineering construction.
Secontly, professional k span,super span and ubm machine series.
Thirdly,we could contract your project and offer technicians to your place for at least 10,000square metres steel engineering construction,so in this process,you will know all about our machine and steel engineering.
We could make UBM Ultimate Building Machine with connected with screws like you could see in this video

UBM Ultimate Building Machine.
This patented, state-of-the-art technology uses an integrated microprocessor
to produce unique structures from various designs with ground-to-ground,
self-supporting panels that require no beams, trusses, columns, nuts, bolts,
fasteners, screws or sealants. An array of ancillary support equipment accompanies
the UBM as well as proprietary design and cost-analysis software.
The UBM mobile factory contains integrated technology for remote programming
and even adjustment by the M.I.C. factory, thousands of miles away.
The UBM meets high safety standards including European CE compliance.
UBM buildings are virtually maintenance-free, since they are watertight,
rust-free, earthquake and fireproof. Buildings manufactured with the UBM outperform
most structures with their proven functionality in severe weather
conditions (heavy snow and typhoons).
