Engineering capability in architectural metal mesh is not measured by the length of a specification table. It is measured by the ability to read a structural drawing, identify the risks that are not stated, and define a system that performs as intended across the full project lifecycle. That is the standard we apply to every project we take on.
JBL Metal accepts and works from four types of project documentation. Each requires a different interpretation approach โ and in each case, the output is the same: a defined structural mesh specification confirmed in writing before any sample or production work begins.
Full-scale architectural drawings showing facade geometry, panel layout, structural fixings, and interface details. We extract dimensional data, identify fixing point requirements, and define the mesh specification to fit the drawn geometry with appropriate tolerances.
Structural drawings specifying load requirements, connection details, and interface geometry. We cross-reference the structural specification against our system capability โ wire diameter, open area, and edge treatment โ to confirm structural compliance before production.
Equipment drawings showing component interfaces, assembly sequences, and dimensional constraints. We define mesh components to fit the equipment interface precisely โ including edge treatment, fixing geometry, and dimensional tolerance stack-up against the assembly drawing.
Sketch drawings, concept documents, or written project briefs that define intent but not final geometry. We assess feasibility, identify the parameters that need further definition, and provide a structured list of questions โ so the project moves forward without assumptions.
Material grade selection is not a product preference โ it is an environmental assessment. The wrong grade does not fail immediately. It corrodes gradually, becomes visible over 12โ36 months, and by then it is an installed facade that requires remediation. The cost difference between SS304 and SS316 at the production stage is 15โ25%. The cost difference at the remediation stage is an order of magnitude higher.
Full Material Guide โSalt-laden air deposits chloride ions on the mesh surface. SS304 will show pitting corrosion within 12โ24 months. The molybdenum in SS316 forms a more stable passive oxide layer that resists chloride attack significantly longer under equivalent exposure conditions.
Pool environments combine high humidity with chlorine-based sanitisation chemistry. Chlorine compounds attack passive oxide layers on stainless steel. SS316L โ the low-carbon variant โ provides better intergranular corrosion resistance in chemically aggressive aquatic environments.
In climate-controlled interior applications without chemical exposure, corrosion resistance requirements are significantly lower. SS304 provides adequate service life. Aluminium offers a weight advantage for large-span ceiling systems where structural load is a design constraint.
Beyond material grade, four structural decisions determine whether a woven mesh system performs as specified across its service life. Each is assessed from the project drawings before specification is confirmed. None of these decisions are made based on catalogue assumptions.
Edge treatment affects structural performance at the mesh boundary โ the point of highest stress concentration. Welded edges distribute load across a continuous weld. Folded edges create a double thickness at the perimeter. Loop edges maintain mesh flexibility. The choice depends on panel size, framing method, and thermal expansion path.
Open area percentage and wire diameter jointly determine structural behaviour under wind load. Larger apertures reduce wind resistance but also reduce mesh structural stiffness. The aperture-to-wire ratio is calculated against the structural engineer's wind load specification and confirmed against the framing grid shown in the drawings.
Woven metal mesh has inherent production variation. For single panels, a ยฑ3โ5mm tolerance band is manageable. For multi-panel facades, accumulated tolerance across 20 or 30 panels can produce a joint line misalignment that is visually significant. Production sequencing and panel labelling are planned from the drawing before production begins.
Mechanical finishing (brushed), electrolytic polishing (electropolished), and passivation all produce different surface roughness profiles and oxide layer characteristics. Surface roughness affects both aesthetic appearance and corrosion resistance โ rougher surfaces accumulate contamination and retain moisture. The appropriate treatment is specified from the application environment, not from aesthetic preference alone.
Production capability defines the boundary within which system definition operates. All parameters below are the verified ranges available across our manufacturing capability. Specific system specifications are defined from project drawings within these boundaries.
Each surface treatment produces a different visual and performance outcome. The selection is made from the application environment and aesthetic specification in the project drawings โ not from a standard options list.
The natural surface produced by the weaving process. Consistent metallic appearance with slight directionality from the wire drawing process. No secondary finishing applied. Most economical option.
Mechanical abrasion produces a uniform directional grain pattern. Reduces surface reflectivity and creates a consistent architectural appearance. The most common finish for interior and sheltered exterior applications.
PVD coating deposits a thin ceramic layer on the mesh surface, producing both decorative colour (brass, bronze, black, gunmetal, gold) and improved surface hardness. The coating also enhances corrosion resistance in moderate environments.
