Lacings are structural cross-bracing components in lattice booms that provide diagonal reinforcement to resist buckling and torsional loads.
Lacings are diagonal or cross-shaped structural members in lattice boom construction that connect main chords to form triangular truss patterns. They transfer shear forces between chords, increase moment of inertia, and prevent local/global buckling under compressive and bending loads. Critical for maintaining geometric stability and load distribution in telescoping or fixed lattice sections.

Lacings provide diagonal reinforcement to form stable triangular truss patterns, transferring shear forces between main chords and preventing buckling under compressive and bending loads.
They are connected via bolted joints (using high-strength bolts) or welded fillet joints, following standards like AWS D1.1 for welding or ISO 898-1 for bolting.
High-strength low-alloy steel (e.g., ASTM A572 Grade 50) with corrosion protection like hot-dip galvanizing or epoxy coatings, ensuring durability under outdoor and heavy-load conditions.
