Systèmes de corrosion atmosphérique pour l’acier de construction
Commencez ici pour l'acier exposé où la classe de corrosion, la préparation de la surface et la sélection du système de guide de durée de vie.
Normes applicables
Orientation rapide du revêtement
Commencez ici avant la qualification technique
Utilisez ces premières orientations pour choisir une famille de revêtements. Le système final dépend toujours du support, de la préparation de surface, de l’exposition, des normes et des documents.
Indoor structural steel in low-corrosion service
Alkyd primer/topcoat for economy, or epoxy primer plus epoxy topcoat for higher durability
Use as a quick first split between low-cost indoor work and more durable industrial indoor steel.
Exemples de produits à vérifier
Outdoor steel workshops, exposed steel buildings, and general pipe racks
Epoxy zinc-rich or epoxy primer plus epoxy MIO intermediate plus polyurethane topcoat
Use as the default industrial anti-corrosion direction for atmospheric steel exposure.

Détails de qualification technique
Pour qui
- Steel buildings
- Pipe racks
- Outdoor structures
Actifs et supports
- Steel buildings
- Pipe racks
- Outdoor structures
- Substrate: Carbon steel
- Substrate: Shop-primed steel
Risques de défaillance courants
- Atmospheric corrosion
Questions de sélection
- What asset is being protected, and is it new build, factory finish, or maintenance?
- Which exposure risks matter most: corrosion, UV, water, chemicals, abrasion, heat, fire, hygiene, VOC, or throughput?
- What result should be optimized: lowest initial cost, balanced protection, longer maintenance interval, production speed, lower VOC, appearance, or surface-tolerant maintenance?
- Which cooperation route fits the buyer: product supply, system package, OEM, distributor, project support, or local supply-chain collaboration?
Préparation de surface
- Confirm substrate condition, oil, salts, dust, rust, laitance, old coating, and surface profile
- Match preparation grade to the selected system and expected durability
- Run adhesion or compatibility checks when old coating remains
Conditions d’application
- Confirm substrate temperature, ambient temperature, humidity, dew point margin, ventilation, and drying window
- Review film thickness, recoating interval, pot life, and handling time from current TDS
Couleurs et conditionnement
- Standard colors and practical finish targets can be reviewed before quotation
- Special colors, gloss, texture, and private-label packaging need sample or batch confirmation
Documentation disponible
- Current TDS
- SDS request
- Packaging and shelf-life check
- Export document review
- Basic application notes

Systèmes Essential / Standard / Extended
Essential
Lowest practical initial cost where exposure and durability requirements are moderate.
- Confirm substrate and preparation level
- Use a simple primer and finish route suitable for the service class
Final product selection depends on current TDS and project constraints.
Standard
Balanced protection, application practicality, and document support for normal commercial procurement.
- Confirm primer and topcoat compatibility
- Use a system schedule matched to exposure and handling needs
Recommended as the default review route for most inquiries.
Extended Service
Longer maintenance interval, stronger weathering resistance, or more aggressive exposure.
- Increase barrier build where justified
- Use higher durability finish options when UV or color retention matters
Requires stronger review of surface preparation, inspection, and film build.
Parcours d’approvisionnement et de partenariat
Route B: System Package Supply
Primer-intermediate-topcoat sets, floor systems, corrosion systems, quantity estimation, and system sequence requests.
System schedule · Product matching · Theoretical consumption · Application sequence · Basic quality-control checklist
Route E: Project & Tender Support
EPCs, general contractors, asset owners, designers, specification teams, and major maintenance projects.
Specification review · System recommendation · Document package · Samples · Project quotation · Local installation and site service by qualified partners
Ce que Qilu peut fournir
- Supply confirmed Qilu product options after review
