Define The Complete Railing Assembly
Start by identifying whether NWW is supplying infill panels for a railing by others or reviewing a broader custom scope. Show the posts, top and bottom rails, panel openings, and the proposed attachment locations. For retrofit work, include photographs and measured dimensions of the existing railing.
The panel, its frame, its attachments, and the surrounding railing work together. A mesh selection alone does not establish the performance of the finished assembly. Provide the project’s opening limitations, loading requirements, material requirements, and other design criteria so the responsible design team can coordinate the complete system.
Distinguish Opening Size From Panel Size
Label whether each dimension is the clear opening between rails and posts or the finished outside dimension of the panel. Show the intended clearance around the frame and the attachment space. Do not subtract a guessed allowance from every opening; the required fit depends on the connection detail.
Identify repeated panels and unique panels separately. A panel schedule with an identification mark, width, height, quantity, and location is useful for quoting and subsequent drawing review. Record out-of-square conditions where an existing opening varies. Field measurements should use consistent reference points so the schedule and drawings describe the same geometry.
Document Sloped And Shaped Panels
Stair infill needs more information than a nominal width and height. Show the slope, vertical and horizontal reference dimensions, corners, and the relationship to the stair rails and landings. Mark the intended orientation of the mesh and distinguish left-hand and right-hand conditions when the layout requires them.
For shaped or irregular openings, provide a dimensioned drawing or an agreed field template. Photographs help explain the location but do not replace dimensions. Keep revision marks on the schedule so a changed stair condition is not confused with an earlier panel size.
Specify The Mesh And Frame Together
State the required welded, woven, or other infill pattern; opening size; wire diameter or gauge; material; and frame detail. Use the railing infill panel product page and wire mesh selections to discuss available construction. Supply the written specification when matching an architect’s selection.
When replacing existing panels, include close photographs of the mesh, frame corners, and attachments. Similar-looking mesh patterns can have different wire sizes and opening dimensions. If a sample is needed for appearance review, identify that requirement before finalizing material and finish.
Resolve Attachments And Exposure
Show where and how the panel is intended to connect to the surrounding structure. Identify attachment holes, tabs, clips, or other specified connection features with dimensions and quantities. Clarify which components and installation work are included in each supplier’s scope.
Describe interior or exterior exposure and any special environmental conditions. Include the finish system and color, and identify requirements for coordinating dissimilar materials. The project team should review corrosion protection and the complete connection detail for the actual installation. Do not assume an interior finish is suitable for an exposed exterior railing.
Send A Coordinated Panel Package
For a useful quote, send plans or elevations, the panel schedule, dimension references, mesh and frame requirements, connection details, material, finish, quantity, delivery location, and schedule. Clearly identify work by others and any engineering or submittal requirements in the project specification.
Download the railing brochure and sketch sheet from the resource library or send your drawings through the project quote form. For related work, review wire mesh stair enclosures and bridge panels. Each application needs its own dimensions and assembly review, even when the mesh appearance is similar.
