Procuring structural grating involves navigating several industry pain points:
- Inconsistent Quality & Dimensional Variance: Receiving batches that don't meet stated load ratings or have poor weld integrity, leading to safety risks and project delays.
- Opaque Pricing & Hidden Costs: Quotes that exclude logistics, duties, or necessary finishing, complicating budget forecasts.
- Long, Unpredictable Lead Times: Factory delays disrupting critical path construction or maintenance schedules.
- Limited Customization & Poor Communication: Inability to adapt to specific project needs (size, finish, packaging) and slow response times from suppliers.
- Certification Uncertainty: Lack of verifiable mill test reports or compliance with international standards like ASTM, CE, or ISO 9001.

W 19-4 Welded Steel Grating: Technical Specifications
The "W 19-4" designation follows a common industry format indicating a welded grating with a specific bearing bar configuration. Here are the typical specifications we manufacture:
| Parameter | Typical Specification | Notes / Standards |
|---|---|---|
| Bearing Bar Size | 1" x 1/4" (25mm x 6mm) | The '19' often refers to the approximate depth in 1/16ths of an inch (19/16" ≈ 1-3/16" or 30mm). The '4' may indicate bar thickness or a series. |
| Bearing Bar Spacing | 1-3/16" or 1-5/16" center-to-center (30-33mm) | Custom spacings (e.g., 15/16", 1-1/16") available upon request. |
| Cross Rod Diameter | 1/4" or 5/16" (6mm or 8mm) | Welded at every bearing bar intersection for strength. |
| Panel Sizes | Up to 10ft x 20ft (3m x 6m) standard | Cut-to-size and tailored panel dimensions are standard for OEM/ODM design projects. |
| Material | Mild Steel (A36/Carbon Steel), Stainless Steel (304, 316) | Complies with ASTM A36, A1011, or relevant ASTM A240 for stainless. |
| Standard Finish | Mill finish, Hot-Dip Galvanized (HDG) to ASTM A123 | Powder coating, painted, or other anti-slip surfaces available. |
Note: The above specifications are typical. Please refer to the actual technical data sheet and order confirmation for project-specific parameters, as customization may alter values.
Load Capacity & Compliance
Our W 19 4 grating is engineered for industrial duty. Load-bearing calculations are performed based on your specific span and loading requirements (uniform or concentrated). We can provide structural calculations and support documentation. Our manufacturing processes and quality management system are aligned with international standards, and we can supply products meeting relevant CE marking requirements for construction products and ISO 9001 quality management principles. Material certifications or mill test reports are available upon request.
Key Buyer Terms: MOQ, Delivery, Logistics & Support
Transparency in commercial terms is critical for efficient procurement. Below are our standard terms, subject to final quotation based on project specifics.
- Minimum Order Quantity (MOQ): Typically 1x20' container load for standard items. Smaller trial orders or sample requests are negotiable, especially for potential OEM/ODM partnerships.
- Lead Time: Standard specification items: 15-25 days after order confirmation and deposit. Customized orders: 25-35 days. Expedited production is available for urgent requirements, contributing to high-speed delivery solutions.
- Packaging: Bundled securely with steel straps and protective corner guards on wooden skids or pallets, ensuring safe ocean or land freight transport. IPPC/ISPM 15 compliant wooden packaging is standard for export.
- Payment Terms: Common terms include 30% T/T deposit, balance against copy of Bill of Lading. L/C is also acceptable.
- Shipping & Incoterms: We expertly handle inland logistics and port formalities. Standard offerings are FOB Tianjin/Xingang, Shanghai, or Qingdao. CIF to major global ports can be arranged.
- After-Sales & Warranty: We provide comprehensive product documentation. A standard warranty covers manufacturing defects. Our team offers technical support for installation guidance and specification questions.

Verified Customer Feedback
Here is what some of our international clients say about their experience sourcing industrial grating from Jinzehong:
"We ordered 8 containers of W19-4 galvanized grating for a refinery expansion project in Texas. The technical drawings were followed precisely, and the galvanizing quality was uniform and met ASTM specs. The logistics were smooth, arriving on schedule at Houston port. Their communication was proactive throughout."
– Michael R., Project Procurement Manager, Industrial Contractor, USA

"As a sourcing agent for European distributors, I need suppliers who are consistent. Jinzehong has been our go-to for welded grating for three years. Their quality control is noticeable—minimal warping, clean welds. Their ability to handle odd-sized panels for specific European standards saved us time and cost."
– Sarah L., Sourcing Agent, Trading Company, Germany
"We required a custom powder-coated color for an architectural facade project in Dubai. The ODM support was excellent—they provided samples, adjusted the panel dimensions for our framing system, and the packaging prevented any transit damage. A reliable partner for customized metalwork."
– David K., Brand Owner, Architectural Products, UAE

Frequently Asked Questions (FAQ)
What does "W 19-4" mean in grating?
"W" stands for Welded. The numbers often refer to the bearing bar depth and thickness in sixteenths of an inch (e.g., 19/16" depth) and a series or cross rod designation. Exact dimensions should be confirmed with the manufacturer's detailed specs.
What is the standard load capacity for W19-4 grating?
Load capacity depends on the span, bearing bar size/spacing, and material. For example, a common 1"x1/4" bearing bar on 1-3/16" centers can typically support significant uniform loads over moderate spans. We provide calculated load tables for each project configuration.
Do you provide CE marking and certification?
Yes, we can manufacture grating products in compliance with the Construction Products Regulation (CPR) and supply with CE marking and the necessary Declaration of Performance (DoP) for relevant harmonized standards. This must be specified at the inquiry stage.
Can I order a small quantity for a sample or pilot project?
Yes. While our standard MOQ is a container load for efficiency, we welcome sample and small trial orders, particularly for new partners or custom OEM/ODM design evaluations. Contact us to discuss your specific needs.
What is the difference between hot-dip galvanized and painted finish?
Hot-dip galvanizing (HDG) involves immersing the steel in molten zinc, providing long-term corrosion protection by forming a metallurgical bond. Painting or powder coating provides color and some protection but is generally for less corrosive environments or aesthetic purposes. HDG is standard for heavy industrial use.
