The design goal is clear and functional,leading to a simplified structure for cost reduction.Typically consists of a few columns and a light roof frame,often unenclosed or partially enclosed.Construction is fast,sometimes completed within a day.Offers excellent ventilation,not impeding equipment heat dissipation.One of the most common basic auxiliary facilities on industrial sites.

Spans are usually small,generally 3m to 8m.The roof uses the lowest-cost single-skin profiled sheets.Columns can be circular hollow sections or H-sections.Can be single or double slope based on equipment access needs.Foundations are typically isolated footings.Design primarily considers roof rain/snow and wind loads.
Widely used in all industrial plants to protect critical outdoor equipment like transformers,switchgear,diesel generators,air compressors,central AC outdoor units,and pumps.Also used for carport shades,EV charger canopies,and temporary material covering on construction sites.
