C-Section Purlins C80 For Steel Structure Roof And Wall Support

Extreme Versatility for Multiple Scenarios (Roofs and Walls): Can be used as wall purlins with various wall profiled sheets and sandwich panels, as supports for smallslope shortspan roof panels, and processed into door/window lintels, equipment supports, and interior partition studs—one profile serving multiple component needs.

Light Weight and Lower Overall Cost: Thinwalled lightweight section design uses less steel for the same load conditions, reducing overall building loads and lowering investments in main steel structures and foundations. Lower procurement cost compared to Zsection steel of the same specification, suitable for budgetconscious conventional workshop projects.

FullSection HotDip Galvanizing for Rust Prevention and Durability: Integral hotdip galvanizing provides uniform zinc coating on both inner and outer surfaces, effectively resisting moisture and rust. Standard 120g/㎡ zinc coating meets ordinary plant requirements; in coastal or mildly corrosive environments, 275g/㎡ thickened coating is optional for longterm maintenancefree rust protection.

Factory PreFabrication for High OnSite Assembly Efficiency: Supports CNC prepunching of fixing holes and tierod holes, with precise cuttolength processing. No onsite drilling or cutting is needed. Assembly uses only bolts, eliminating welding and secondary anticorrosion work, significantly shortening enclosure construction periods.

Flexible Installation for Openings, Corners, and SpecialShaped Areas: The regular section allows easy cutting and splicing, making it suitable for door/window openings, wall corners, and interior partitions, complementing Zsection steel where it is less convenient for specialshaped wall locations.

Stable Structure with Excellent ColdFormed Steel Toughness: Combined with tie rods and struts, it forms a stable secondary structural system, providing safe and reliable use in ordinary workshops and warehouses.

Complete Supporting System, OneStop Procurement: Compatible with full accessory sets including purlin brackets, round steel tie rods, sleeve struts, and highstrength bolts. Profiles and accessories share unified anticorrosion standards, eliminating separate procurement efforts.

FAQ

Q1: How to distinguish between Csection and Zsection purlins and when to use each?

Csection steel does not support continuous lapped load transfer; suitable for walls, shortspan roofs within 6 meters with small slopes, lintels, and partitions. Zsection steel supports end nesting/lapping to form continuous beams with stronger bending capacity, mostly used for longspan (>6m) and highslope roofs. For largearea long roofs, Zsection is preferred; for exterior walls and small auxiliary buildings, Csection is preferred.

Q2: Which Csection steel is suitable for coastal or chemical plant areas?

It is recommended to use 275g/㎡ doublesided thickened hotdip galvanized Csection steel. The thicker zinc coating provides significantly improved resistance to salinealkali and acid/alkali corrosion, effectively extending service life and reducing future rust removal and renovation costs.

Q3: Can Csection steel be used in cold storage or clean workshops?

Yes. Use the hotdip galvanized corrosionresistant version with insulated sandwich panels. In highhumidity cold storage environments, upgrading to thickened zinc coating is recommended to prevent longterm corrosion from condensed moisture.

Q4: Can Csection steel be cut or drilled onsite for modifications?

Onsite cutting and drilling are not recommended as they damage the galvanized anticorrosion layer, leading to future rusting. All punching and cutting should be completed in the factory. If onsite cutting is unavoidable, cut surfaces must be coated with zincrich repair paint for corrosion protection.

Q5: Does Csection steel require regular repainting for maintenance?

Standard 40g zinc coating lasts 20 years without repainting in conventional workshops. The 275g thickened coating provides 30 years of rust protection in coastal areas. Only annual simple surface dust cleaning is needed—maintenance cost is extremely low.

Q6: What accessories are needed for a complete secondary structural system?

Supporting accessories include purlin brackets, round steel tie rods, sleeve struts, and M10/M12 highstrength bolts. These can be supplied as a complete package with unified anticorrosion standards for both profiles and accessories, eliminating multisource procurement hassles.

Q7: Can Csection steel be dismantled and reused?

Yes. With bolted assembly and no welding, undamaged profiles with intact galvanized coatings after disassembly can be directly reused for workshop expansions or temporary shed construction, offering high material residual value.
