Fireproof Coating Standards: UL 1709 vs. BS 476 Explained

Choosing a fireproof coating for steel is not only about product type (intumescent vs cementitious) or price—it’s about specifying the right test standard for the fire scenario. The two names that commonly appear in international RFQs are UL 1709 (hydrocarbon pool fire exposure) and BS 476 (building “cellulosic” fire exposure), and confusing them can lead to incorrect system design or failed […]

How to Apply Intumescent Paint over Anti-Corrosion Primer: Compatibility Guide for Structural Steel

On most structural steel projects, intumescent paint is not applied to bare steel — it is applied as part of a tested, approved coating system that includes an anti-corrosion primer and, in most outdoor or semi-exposed conditions, a protective topcoat. System performance under fire exposure depends entirely on those layers being compatible and approved together, […]

What Is Anti-Corrosion Coating System & Why It Matters

In many industrial and infrastructure projects, corrosion protection is often treated as a secondary task—something to be decided after structural design is completed. As a result, terms like anti-corrosion coating, protective paint, or coating system are frequently used interchangeably. This misunderstanding leads to one common outcome:the coating looks acceptable at handover but fails far earlier […]

Epoxy Zinc Rich Primer and Steel Structure Coating System: A Practical Design Guide

In most industrial projects, coating failure does not happen because the coating product is poor quality. It happens because the steel structure coating system — from epoxy zinc rich primer selection through to topcoat specification — was never properly designed as a coordinated system. A primer selected by habit, a topcoat chosen for appearance, and […]

Intumescent Fireproof Coating for Steel: 60/90/120 Min Rating Guide

For structural engineers and project managers, “fireproofing” isn’t just about buying a can of paint—it’s about meeting a specific legal Fire Resistance Rating (FRR) of 60, 90, or 120 minutes. The thickness of the intumescent coating determines whether a steel beam holds up or collapses during a fire. HUILI Coating provides certified thin-film intumescent coating […]

Anti-Corrosion Coating for Steel Structures: How to Choose

Introduction In steel structure projects—whether industrial plants, warehouses, bridges, or offshore facilities—corrosion is rarely an unexpected problem. What often causes serious failure is choosing the wrong anti-corrosion coating system at the beginning. Many projects rely on “standard practice” or price-driven decisions: a generic epoxy primer, a topcoat that looks acceptable, and minimal surface preparation. These […]

Steel Structure Coating Inspection Checklist: Surface Prep, DFT, Recoat Interval & Touch-Up

A steel structure coating system only performs as designed when surface preparation, application conditions, and inspection records are strictly controlled. For industrial anti-corrosion projects, a clear inspection checklist shortens supplier evaluation, reduces rework risk, and ensures long-term protection. HUILI provides not just coatings, but the technical guidance needed to apply them correctly. 1) Pre-job checklist […]

Epoxy Primer Polyurethane Topcoat System for Outdoor Steel Structures

For engineers and procurement teams in the Middle East, Southeast Asia, and Central Asia, selecting the right epoxy primer and polyurethane topcoat system is a direct project risk decision — not just a product choice. This guide covers system selection logic, surface prepar

Anti-Corrosion Coating for Steel Structures: How to Build an Industrial Coating System

Steel structures in industrial facilities face simultaneous attack from corrosion, UV exposure, moisture, thermal cycling, and chemical contamination — a single-product approach to protection fails in almost every industrial service environment. Building a correct anti-corrosion coating for steel structures means designing a multi-layer system where each coat performs a defined function, and where the system […]

Understanding Industrial Coatings: Types, Functions, and How to Select the Right System

Types of industrial coatings cover a wide range of engineered systems designed to protect substrates from corrosion, chemicals, UV radiation, abrasion, and moisture — while also delivering the surface appearance, color, and finish quality that industrial and commercial projects require. In most real-world applications, these two goals are not in conflict: a correctly specified multi-layer […]
