I. 3 Overall Monthly Market Overview

2026 year 3 The month coincides with the peak season for spring infrastructure and steel‑structure projects, as downstream projects resume work at a significantly higher rate. Consequently, demand for steel‑structure‑related ancillary materials is being concentratedly unleashed, and the overall market is showing… “ Demand is recovering, prices are rising steadily, and trading activity remains robust. ”  The situation.

On the raw-material side, costs for resins, steel, copper, and zinc powder have edged up, providing support to the prices of various auxiliary materials. On the supply side, major manufacturers are operating at full capacity, with ample spot inventories and no disruptions in supply or shortages. With both supply and demand driving prices upward, the prices of all four major categories of auxiliary materials have risen slightly, with increases kept within… 1%-5% , the market operated steadily with no significant fluctuations.

II. 3 Monthly Average Quotation Details for Various Auxiliary Materials

(1) Steel structure coatings (Unit: yuan) / kilograms)

(2) Welding wire (unit: yuan) / kilograms)

(3) Welding flux (unit: yuan) / kilograms)

(4) High-strength bolts (unit: yuan) / Set)

III. 3 Monthly Category Market Deep Analysis

(1) Steel Structure Coatings

1. Market Review ：3 Overall, monthly coating market prices remained stable; only fluorocarbon topcoats saw a price increase, driven by a slight rise in the cost of fluorocarbon resin raw materials. 1 Yuan / Kilograms; price fluctuations in other product categories were minimal. With the resumption of construction on downstream steel‑structure factories and venues, demand for anti‑corrosion and fire‑retardant coatings has risen, leading to increased transaction volumes compared to… 2 Monthly improvement 30% Around this time, mainstream brands have ample inventory and stable supply.
2. Influencing factors : Prices for titanium dioxide and epoxy resin remain stable, with no significant cost fluctuations; a rebound in downstream production activity is boosting demand, and a balanced supply‑demand dynamic is supporting a modest price increase.
3. Key Features High-end anti-corrosion and fire-retardant coatings are growing faster than conventional industrial paints, with project procurement placing greater emphasis on product quality and environmental performance.

(2) Welding Wire

1. Market Review ：3 Monthly welding wire prices have risen slightly across the board, driven by higher raw material costs for wire rod, leading to increases in the unit prices of various types of welding wire. 0.1-0.2 Yuan / Kilograms. As steel‑structure fabrication companies resume operations, procurement of welding consumables has surged. Gas‑shielded welding wire and submerged‑arc welding wire, the mainstay products, are in high demand, with manufacturers reporting slightly extended order lead times; however, spot‑stock availability remains unaffected.
2. Influencing factors Steel raw material prices have risen slightly, driving up the production costs of welding wire; meanwhile, downstream processing firms are expanding capacity, leading to a sharp surge in demand for welding consumables.
3. Key Features : General‑purpose welding wire accounts for the largest volume, while demand for high‑strength steel welding wire is steadily rising in tandem with the growth of high‑end steel structure projects.

(3) Flux

1. Market Review : Flux prices have risen slightly in tandem, with month-on-month increases all at 0.1 Yuan / Kilograms; market demand has rebounded as the use of submerged-arc welding and electroslag welding processes increases. The product is primarily used as a consumable for submerged-arc welding wire, with steady transaction volumes. Manufacturers maintain ample production capacity, and prices have been marginally supported by rising costs of raw materials such as quartz sand and additives.
2. Influencing factors : Rising raw material and additive prices are underpinning costs; at the same time, downstream demand for welding processes is increasing, resulting in robust supply and strong demand.

(4) High-strength bolts

1. Market Review ：3 The price of high-strength bolts has risen slightly. 10.9 Unit price of high-end bolts has increased. 0.1 Yuan / set, 8.8 The prices of ordinary-grade bolts remained unchanged. On-site steel structure installation projects have fully commenced, leading to a substantial increase in bolt procurement volumes, particularly for high-end products. 10.9 Demand for Grade bolts remains strong, with manufacturers maintaining ample spot inventory and price fluctuations remaining manageable.
2. Influencing factors : Steel billet costs are rising, and the production costs of high-end bolts remain relatively high; surging on-site installation demand is driving sales growth.

IV. Future Market Outlook ( 4-5 month)

1. Overall trend ： 4-5 The month represents the peak season for steel structure construction, with downstream demand expected to remain robust, and auxiliary material prices are forecast to… The market is expected to remain in a moderately bullish range, with slight and steady upward momentum. , with no significant price cuts expected, the overall increase will be kept within 2% Within.
2. Category-specific forecast ：
   • Coatings: Fluorocarbon topcoats are expected to continue rising slightly, while prices for standard anti-corrosion and fire-retardant coatings remain stable.
   • Welding wire and flux: Supported by rising raw-material costs, prices may increase further. 0.1-0.2 Yuan / kilogram;
   • High-strength bolts: 10.9 Demand for high-end bolts remains robust, with prices likely to edge higher, while ordinary bolts are expected to stay stable.

V. Procurement Recommendations

1. Procurement Recommendations ：4 Monthly stock levels of commonly used specifications can be increased as needed, particularly for epoxy zinc‑rich primers and gas‑shielded welding wires. 10.9 For key products such as high-strength grade bolts, we lock in monthly partnership prices with leading brands to mitigate the risk of subsequent minor price increases.
2. Quotation Recommendation : The project quotation may be moderately increased in line with the rise in auxiliary material costs. 1%-3% , ensuring project profitability;
3. Inventory Control : Maintain safety stock levels for key SKUs to prevent stockouts from disrupting construction schedules, while avoiding excessive inventory buildup and reducing the risk of capital lock-up.
