Frequently Asked Engineering & Export Questions

Are your right-angle and swivel couplers drop-forged?
Yes, our heavy-duty Ø48×48 mm fixed couplers (SM-A641, 1.1 kg), swivel couplers (SM-A642, 1.1 kg), and girder couplers (SM-A645, 1.4 kg) are drop-forged under EN 74 dimensional standards.
What span lengths are available for Lattice Truss Beams?
Both hot-dip galvanized steel (SM-A171) and lightweight aluminium (SM-A481) 45 cm deep lattice beams are stocked in 320, 420, 520, 620, 720, and 820 cm lengths.
Can international buyers import container loads of couplers and screw jacks only?
Yes. Many UK, European, Middle Eastern, and African wholesalers order full 20DC containers packed with SM-A661 steel crates of couplers, base jacks, and tie hardware.
What types of stacking stillage pallets do you manufacture?
Open post pallets in 90 cm and 130 cm heights (SM-F663/F664), closed wire-mesh box pallets (SM-F665/F666), edge panel racks (SM-K667), and solid sheet-steel bins (SM-A661).
Are Z-staircases available in both steel and aluminium?
Yes—both 60 cm and 90 cm wide Z-staircase modules are manufactured in hot-dip galvanized steel (SM-A281/282) and lightweight aluminium (SM-A471/472) for 250 cm and 300 cm bays.
