The cost of structure assembly of steel H-frame structures is estimated to be approximately _________ percent of the standard rigid-lattice work steel tower.

The cost of structure assembly for steel H-frame structures is estimated to be approximately 50% of the cost of standard rigid-lattice work steel towers. This reflects the differences in design and the efficiencies in materials and labor utilized in H-frame structures compared to traditional lattice towers.

H-frame structures generally use fewer resources and less complicated connections than rigid-lattice towers, leading to a relatively lower overall cost. Additionally, the fabrication and assembly process of H-frames tends to be streamlined, which can significantly reduce labor costs associated with construction. Understanding this cost relationship is crucial in project planning and budgeting within the field of construction and maintenance of electrical infrastructure.
