Системы защиты стальных мостов
Маршрут поддержки проекта для мостов и надземных стальных конструкций, требующий графиков нанесения покрытий, документов и проверки спецификаций.
Применимые стандарты
Быстрое направление подбора покрытия
Начните здесь до технической квалификации
Используйте эти первичные ориентиры для выбора примерного типа покрытия. Окончательный подбор зависит от основания, подготовки поверхности, условий эксплуатации, стандартов и документов.
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.
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.
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.
Примеры продуктов для проверки
Bridge deck steel primer or anti-slip friction surface
Сначала квалификацияInorganic 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.

Вопросы для подбора
- 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?
Подготовка поверхности
- 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
Условия нанесения
- 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
Цвета и упаковка
- Standard colors and practical finish targets can be reviewed before quotation
- Special colors, gloss, texture, and private-label packaging need sample or batch confirmation
Доступная документация
- Current TDS
- SDS request
- Packaging and shelf-life check
- Export document review
- Basic application notes

Системы 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.
