FAQ'S

If the concrete thickness is insufficient and no embed is provided, the only option is to bolt through the deck. However, this approach presents challenges, particularly if the concrete is a topping slab or if the slabs are pre-tensioned. Additionally, access to the underside of the deck is necessary, and relieving plates matching the base plates with lock nuts and washers are required.

A minimum 3” surface width is required for mounting the SHOE base. A 2” width is not recommended because engineering often requires additional metal reinforcement, making it more expensive for the customer than using C12x20.7 or a 12”x3” tube.

Yes, it is possible to weld onto galvanized steel, but there are important precautions and considerations to keep in mind:

1. Zinc Coating Hazards:

   • Galvanized steel is coated with zinc to prevent rust.

   • When welded, the zinc coating near the weld area vaporizes, releasing zinc oxide fumes, which are toxic and can cause a condition known as metal fume fever.

2. Preparation:

   • Remove the zinc coating in the weld area (typically 1–2 inches around the joint) using a grinder or chemical stripper.

   • This reduces toxic fume production and improves weld quality.

3. Ventilation and PPE:

   • Always weld in a well-ventilated area or use fume extraction systems.

   • Wear appropriate respiratory protection and protective clothing.

4. Welding Techniques:

   • Common methods include MIG, TIG, and stick welding.

   • Use appropriate filler materials and settings to ensure good penetration and avoid porosity.

5. Post-Weld Treatment:

   • After welding, the exposed steel should be re-galvanized or coated with a zinc-rich paint to restore corrosion resistance.

Yes, stainless steel posts can be welded to steel (carbon steel) stringers, but there are important considerations to ensure a strong, corrosion-resistant, and safe weld:

1. Material Compatibility

• Stainless steel and carbon steel have different chemical compositions, which can lead to issues like galvanic corrosion if not properly managed.

• The most common stainless steels used in construction are 304 and 316 grades.

2. Welding Process

• Dissimilar metal welding is required. This typically involves:

  • TIG (GTAW) or MIG (GMAW) welding.

  • Use of a compatible filler metal, such as 309L stainless steel, which is designed for joining stainless to carbon steel.

3. Preparation

• Clean both metals thoroughly to remove any contaminants, oxides, or coatings.

• Tack welds may be used to hold the post in place before final welding.

4. Post-Weld Treatment

• Passivation of the stainless steel may be necessary to restore its corrosion resistance.

• Consider applying a protective coating to the carbon steel to prevent rust, especially at the weld joint.

5. Structural Considerations

• Ensure the weld design meets load and safety requirements, especially if the posts are part of a railing or guard system.

The minimum recommended radius for bent SHOE and glass is 5'-0". A 3'-0" radius can be achieved; however, it poses a risk of glass breakage and metal distortion.

Yes, however there are certain types of sealants that should be avoided:

1. Acid-Cure (Acetoxy) Silicone Sealants

   • These release acetic acid during curing, which can corrode aluminum over time.

   • Often have a vinegar-like smell.

   • Not compatible with most metals unless specifically formulated.

2. Polyurethane Sealants (Unmodified)

   • Some types can react with aluminum, especially in moist environments, leading to corrosion.

   • They may also not adhere well to anodized or coated aluminum surfaces.

3. Butyl Rubber Sealants

   • These can stain or degrade aluminum finishes and are not recommended for visible or exposed applications.

4. Latex or Acrylic Caulks

   • These are not durable enough for exterior or structural applications and may fail under UV or moisture exposure.

5. DOW 795 Is deemed an Excellent Sealant for use with Aluminum Glass Guardrail Shoe Moldings

For SHOE, VIEW, SOLO, and VISIO railing systems, where glass panels act as structural balusters:

• If the glass is ½” tempered laminated (interior or exterior), SGP (SentryGlas Plus) is required.

• If the glass is 5/8” or ¾” tempered laminated (interior only), PVB (Poly Vinyl Butyrate) can be used.

• For exterior applications, SGP must be used to prevent delamination.

• The typical interlayer thickness is .060 inches, but this may vary depending on project specifications, wind loads, and location (e.g., hurricane/wind borne debris regions).

• 

The fascia mounting brackets are 5” x 5” square.

½” Aluminum Laser Cut Patterned 

The handrail brackets are attached to the infill panels. The current post height is calculated as panel height minus 18”, which often makes the posts too short for bracket attachment. Older project photos showing brackets attached to posts are exceptions.

Yes, using custom VIEW mounting buttons, it can be reduced to no less than 1”

Yes, ANY of the VIVA Systems can be specified with wood handrails or top rails - Maple, Cherry and Red Oak are standard offerings in 2” Diameter,  or custom shapes as specified; however other species are available if specified. Wood products are typically provided UNFINISHED by VIVA, to be finished BY OTHERS. If the wood products are to FSC (Forest Stewardship Council), SFI (Sustainable Forestry Initiative) or other conservation program materials, they need to be clearly specified as such.

Post spacing up to 4’-0” on center can use 1.5” diameter posts, anything exceeding 4’-0” on center up to 5’-0” on center maximum will require 2” diameter posts. A 1.5” Diameter top  rail may be used for all of these conditions. 

Yes, LED lighting can be provided in the SHOE base  Color: 3000K Warm White or 4000K Cool White Output: Medium: 3 Watt/ft – 185 lumens/ft. High: 5 Watt/ft – 250 lumens/ft.

Yes, all VIVA LED Products meet the 1 Foot Candle requirement. 

No, VIVA Railings does not sell any LED lighting components (i.e. PODS, Linear) by themselves, that is, as the LED fixtures only, but only as integrated into complete railing systems, whether they be handrails, top rails, free standing site rails, wall rails or base shoe lighting.

There is no limit to the length of the railing, but the railings are divided in 25’-0” segments between placement of end posts- for example, a 75’-0” railing would be divided into (3) 25’-0” segments with (2) support posts. 

Yes, the SLAT System can be bent to a radius (in the FLAT) minimum inside radius is 24”

No, the FRAME System is generally designed to be used in linear applications (straight lines) however, 90 degree corners can be achieved, and used on stairs with a fair amount of difficulty involved, and not recommended for this application.

Yes, The FOLD Panels can be Pre-Fabricated to a minimum radius (FLAT) of 44”Bending is done prior to Powder Coat Painting

14 gauge in Stainless Steel (.078) 11 gauge in Aluminum (.125) 

The smallest hole size for Laser Cut Panels is 1” Diameter

Yes, 2” wide HSS stringers can be used. However, if an architect specifies C Channels, they must provide the exact flange width for precise compatibility.

Yes, this will be sufficient clearance

Yes, PVB can be used in post-supported interior railing systems, where glass serves as an infill panel rather than a structural baluster.

What are the Levels of Translucency in interlayers?

1. High Translucency (e.g., 85%): Allows most light to pass through while slightly diffusing it. This level is often used in areas where natural light is desired, but some privacy is needed 

2. Medium Translucency (e.g., 50-70%): Balances light transmission and privacy. Suitable for spaces like conference rooms or partitions where moderate privacy is required 

3.  Low Translucency (e.g., 30-50%): Allows less light to pass through, providing higher privacy. Commonly used in areas like bathrooms or private offices 

 Opaque (e.g., 0-20%): Blocks most light, offering maximum privacy. Ideal for spaces requiring complete confidentiality 

No, VIVA generally provides a sacrificial weld plate which is drilled and tapped to receive the mounting bolts. The plates are ½”x5”x5” to match the post mounting bracket back plates

Yes, VIVA Railings has a licensed engineer in Ontario, Canada.

Besides a Notice of Acceptance (NOA), there are several other levels and types of product approvals used in the construction and building materials industry, particularly in Florida and other regions with strict code requirements. Here's a breakdown of the main types:
