2026 year 6 Since [month], housing and urban–rural development bureaus and fire‑inspection authorities across the country have issued a series of documents to strictly regulate the selection of fire‑retardant coatings for steel structures and on‑site construction management, addressing longstanding industry issues such as non‑compliant coating choices and substandard material usage. The new regulations clearly set out core selection criteria: the design fire‑resistance rating of structural members must exceed… 1.5 For short durations, the use of intumescent fire‑protective coatings is not recommended; for fire‑resistance ratings greater than 2.0 hour, The use of intumescent fire‑protective coatings is strictly prohibited. 。
Meanwhile, the authorities require that construction drawings precisely indicate the fire-resistance rating of components, the type of coating, and the standard coating thickness, and strictly prohibit construction and supervision entities from unilaterally altering fire‑protection design parameters. All fire‑retardant coatings entering the site must be verified as valid. CCCF Certification certificates and retained samples are archived, and routine on-site physical inspections of coating thickness are conducted. For key projects such as factory buildings, warehouses, and large‑span steel structures, any instances of non‑compliant use of substandard coatings or reduced coating thickness will be subject to rework orders, and the responsible entities will be held accountable, thereby significantly enhancing the standardization of construction practices across the industry.
