Sizing / Forming

It is product dependent. Refer to the typical sizes for each standard product. Guardrails and fences are typically 4’ width max. Oversized sheets are available, but there is an added cost, and potential engineering limitations.

Our systems are designed to reduce or eliminate secondary structural support. Our brake-formed return flanges on panel edges increase the structural integrity of the panel face and gives the optimal hardware attachment point. We have pre-designed/engineered brackets for mounting formed panels. Please see the standard product pages for details and corresponding bracket type in downloadable product sheet.

Finish

The most popular finish we provide is architectural rated powder coating that complies with AAMA 2604. Typically a 2-coat process, primer plus color top coat, and available in a wide array of standard pallet colors from various industry suppliers. Standard finishes come with a 5 year color and gloss warranty.

We also offer AAMA 2605 Fluoropolymer finishes in either powder coat or liquid applied (Kynar or equal). Color matching is available in liquid applied Kynar. Limited 10 to 20 year warranties are available. Some colors may have extended lead times.

Anodize finish options include clear and dark bronze only.

Lead Time

After the final shop drawing approval, with final field verification, it is approximately 5-7 weeks with powder coating; 7-8 weeks with Anodize or Kynar finish.

Installers

BOK Modern is material supply only, but in California and some US metro areas, we can provide a list of preferred installers. Please inquire.

Our products are very easy to install. We can work with your installer or miscellaneous metal team by walking them through the installation methods via video call or conference call. See installation videos found on each product type page.

Samples

Due to our large pattern library, we don’t stock samples of every pattern. Please inquire about a pattern you like and we can propose a similar one we have in stock.

We can produce made to order samples in one of our standard patterns, or in a custom pattern (.DXF vector file required) at 24”x 24” with pattern at full scale. Made to order samples are $250 unfinished and take approximately 2-3 weeks, or finished in a standard stock color for $400 in approximately four weeks.

Yes, you can order color chips. Please note that lead time for each color sample is as following:

– Powder Coat from preferred suppliers: 3-5 days for in stock* (up to 3 color selections)
– Fluoropolymer**: 10-15 days (up to 3 colors in PPG / Duranar / or equal)
– Anodizing: 5-7 days (for clear or bronze anodize)

* Out of stock colors may have to be sourced from the supplier with 10-20 day lead times.
** Custom colors paint chips will be provided when needed for contracted projects.

Please contact BŌK Modern if you need special samples ordered for a specific project.

Pricing

Please provide all relevant drawings (plan, elevation, section, detail, etc.) and specs (material, thickness, finish, and pattern) to ensure the most accurate estimate. Please note that we cannot provide a final estimate or go into contract until a 100% CD plan set is provided. Our estimate lead time is approximately 5-10 business days depending on the complexity of the project.

Please provide your SD or DD package for a ROM number. This has a much faster lead time.

Volume

Yes, currently we have a $15k minimum order, and this equates to at least 4-6 full size panels typically.

Patterns

On each pattern’s page, the rough scale of the pattern is shown by the human figure behind the panel. We can provide the pattern CAD file upon request for design development per standard dimensions. It may be possible to scale patterns up or down to the client’s liking, but consult with BOK Modern for any limitations. Scaling a pattern down to have more numerous and smaller perforations does increase the cost.

Yes, all stock patterns can be flipped, mirrored, rotated, and even scaled. Scaling patterns down does add cost due to longer machine time processing. Not all patterns can be scaled.

Yes, please send us a .DXF of the vector work (arcs- not splines or polylines). We will then evaluate it for pricing, and advise on needed alterations when appropriate.

It depends on the pattern. If the custom pattern requires added laser time, the cost will increase. In many cases custom patterns do not add cost. If we are unable to fabricate the custom pattern provided, we would recommend ways to make it work by providing our fabrication guidelines. If you do not have a .DXF of the vector work, our design team can create this file, but as an added design service cost.

Patterns are priced according to production run time. Limited perforation patterns are less expensive. More intricate patterns cost more. The delta is usually a 20% difference between simplest and most complex.

The minimum perforation size needs to be at least 2x the material thickness. So, 3/8” opening on 3/16” material. There is no max perforation size, except where code dictates – e.g. 4” sphere rule for guardrails. The webbing or material between perforations also needs to be 2x material thickness or greater for strength and to reduce deflection on the panel face. Long slots that cross most of a panel face can weaken the panel and may not be workable without modifications to ensure panel integrity.

Simple patterns that have a standard, geometric design are the least expensive when laser-cut. Examples are: A18, B9, and B21.

We cannot guarantee that any of our patterns are not climbable. However, we can suggest vertical patterns with fewer openings that are less conducive to climbing. While each jurisdiction will have its own unique code, we are often able to alter a pattern from our library that would discourage climbing. Scaling down with more perforations may increase the cost of fabrication.

Sometimes code requires a 50% opening. Pattern information on our website indicates approximate percent open area. Some standard and custom patterns may be altered to achieve a 50% opening by altering the size and spacing of perforations.

For all patterns contained on the panel face, the minimum solid border or margin is 3/4” all around.

It is possible for some patterns to eliminate the borders and bleed the pattern around the formed edge of the panel for a seamless look. Consult with BŌK Modern for any limitations.

Each pattern page shows the approximate % of open area for the selected pattern. If you like a specific pattern and would like more % opening, some customization may be possible. Code compliance factors may limit modifications. A 4” maximum opening for balcony guardrails or long slots that allow too much deflection of the panels are typical limitations.

Design Service

We provide design-assist service during the estimating phase, including design charettes and technical and pricing exercises. We provide a design contract for projects that require more extensive design exploration for a longer period and for highly custom projects. Design contracts may also be required for engineering situations outside of typical conditions. Please inquire for a design contract assessment of your project.

Please inquire with us to setup a design consult or zoom charette.

Specification of BŌK Modern products

Cost effective projects make the most practical use of raw material sheet sizes. Configuring panel sizes that include face and edge forming to fit standard sheet sizes while satisfying engineering requirements can avoid excess waste.

Standardizing panel types as much as possible can save on design and documentation time. More units of fewer types drives cost down. Use a standard pattern and panel repeat vs. a continuous custom pattern image with many one-off panels. Each change in panel type, face size, variation in pattern, or edge detailing creates added panel types resulting in added costs.

Simple geometric shapes and moderately sized openings are more efficient to cut. Please see pattern library for our standardized patterns or contact BŌK Modern to talk you through guidelines for designing a custom, cost effective pattern.

Panels with the exact same features (size, material, forming, finish, color, pattern layout, orientation, etc.) are considered the same ‘type’. Changes in any panel feature will result in a different panel type. More panel types equates to more hours for shop drawings and programming for fabrication resulting in higher costs.

We have lines of standardized products with pre-engineered details and mounting brackets. Our standardized product lines are:

– Guardrails
– Façade Cladding
– Canopies
– Shades
– Fence
– Products
