Systèmes de protection de l'acier des ponts
Itinéraire de support de projet pour les ponts et les structures métalliques surélevées nécessitant des calendriers de revêtement, des documents et une révision des spécifications.
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.
Bridge steel box girders, bridge attachments, guardrails, and exposed bridge steel
Epoxy zinc-rich or inorganic zinc primer plus epoxy sealer/MIO intermediate plus polyurethane or fluorocarbon topcoat
Use when bridge owners need a multi-layer system and documentation before pricing.
Exemples de produits à vérifier
Municipal viaduct steel and bridge-adjacent steel in atmospheric exposure
Solvent-based or waterborne zinc/epoxy primer plus epoxy MIO intermediate plus polyurethane or fluorocarbon finish
Use when the buyer asks for bridge or viaduct protection but has not yet decided solvent-based versus waterborne documents.
Exemples de produits à vérifier
Sealed bridge-box interiors and enclosed steel cavities
High-build epoxy, with zinc-rich primer considered when specified
Use when the surface is enclosed and the main need is barrier protection rather than decorative weathering.
Exemples de produits à vérifier
Bridge deck steel primer or anti-slip friction surface
Qualification d’abordInorganic zinc or epoxy zinc-rich primer after specification review
Use for bridge deck primers, bolted friction surfaces, or other areas where coefficient/friction requirements may be specified.

Détails de qualification technique
Pour qui
- Highway bridges
- Railway bridges
- Overpasses
Actifs et supports
- Highway bridges
- Railway bridges
- Overpasses
- Substrate: Blasted steel
- Substrate: Shop-primed steel
Risques de défaillance courants
- Atmospheric corrosion
- UV and weathering
- Water or immersion
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 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
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
Ce que Qilu peut fournir
- Supply confirmed Qilu product options after review
- Provide current TDS/SDS and export document support when available
- Prepare starter system schedules and theoretical consumption references
