The Phil Hardberger Park Conservancy sits on the old Voelcker Dairy Farm in north-central San Antonio. The 330-acre natural park is well-known as an urban oasis featuring a nature center, outdoor classrooms, dog parks, play and workout areas, walking, hiking, biking trails, and a managed wildlife habitat. 

A masterplan community called Churchill Estates with moderately priced homes sits adjacent to the park. The property owner’s house was built on a bluff overlooking the park and is not included in the neighborhood homeowner association.


The current homeowner spotted a Texas Railing Systems truck at a Home Depot parking lot in Kerrville, about an hour northwest of San Antonio. “He took a picture of our truck door, and two years later, he called for us to provide the railing for his home,” said Wayne Uecker, owner of Texas Railing Systems. 

The Texas Railing Systems crew also completed a tree top skywalk in Hardberger Park as part of a 150-foot land bridge for wildlife crossing over Wurzbach Parkway, connecting the two halves of the original dairy farm land.  

Uecker uses CR Laurence as the framework and Ultra-tec Invisiware® as part of their in-house product designs on most projects. His team installed both for this project. “The ease of use is great because it’s incorporated into our standard fabrications, and we understand the Invisiware system,” said Uecker.

Texas Railing Systems is a leading architectural, contemporary railing specialty company with more than one thousand projects throughout the Texas with long-standing commercial, residential, and manufacturing relationships, including their long-time supplier, Cable Art.    

Much of the country’s workforce is transitioning back to office spaces after more than a year of working from home, and workers’ expectations have changed. In response, business and commercial property owners, designers, and architects are now modifying their approach to better accommodate the preferences of their staff and tenants.

Even well-respected brands like Steelcase are acting on recent studies explaining the shifting outlook of employees. They’re now reimagining their offerings to ensure that companies create spaces where their staff can feel most comfortable and productive.

Here, we’re sharing four office trends that you’ll want to consider.

The Rise of Resimercial

According to the experts at Wayfair, Resimercial workplace design is here to stay. Employees expect a comfortable place to spend their workdays; for employers, creating these hospitable – even fun – spaces help to ensure happy, more engaged workers.

Millennials and Gen Z, now most of the nation’s work population, are leading with a “work any time, any place” mindset and want a workspace they can feel at home. Typical Resimercial contains breakout spaces with a style that involves a mix of textures and silhouettes, house plants, comfortable seating, durable upholstery, and natural fibers.

A Room with a View

Gone are (or should be) the days of working in an office made of four solid walls. Creating additional outdoor spaces, bringing the outside-in by integrating biophilic elements, or emphasizing daylighting by implementing walls made of windows, has the power to transform the work setting by reducing stress and enhancing the mood.

While windows certainly play a central role in helping to lighten up an environment, there are other ways to reimagine a conventional office space, create open areas and improve line of sight.

Add Texture: Combine the Old with the New 

Incorporating various textures and textiles in the design or accessorizing of an office can add life and a sense of interest to a space. According to Parterre, blending old and new elements – including a mix of different metal finishes – can create an alternative style that delivers a warm feeling to what may have traditionally been a run-of-the-mill atmosphere.

Ultra-tec’s mix of finishes and accessories (including bronze) pair beautifully with wood, stone, and other natural materials that offer a diverse range of design options.

Opt for Sustainability 

The choices you make when planning your space matter to your team. According to Allwork and a survey by Fast Company, sustainability is an important criterion for today’s workforce. The cable railing from Ultra-Tec is environmentally friendly, there is little waste in the product, and it is 65% recyclable. Selecting alternatives that support the environment demonstrates to employees that you’re a company that cares.

Ultra-tec stainless steel cable railing products are an excellent choice for a variety of commercial designs, offering unobstructed views and a spacious appearance. The most common use of cable railings in designs today are horizontally run cable railing system for interior and exterior applications.

The use of cable railings for commercial projects offer architects and designers flexibility, versatility, and a modern approach to any design. Cable railings also allow a creative and easy to install alternative for fabricators and installers. In addition to design and creativity, there are key design considerations for a successful cable railing system installation.

Stainless-Steel Cable Railing Strength

Cable, also referred to as wire rope or aircraft cable, is very strong in tensile strength and is designed to be flexible. The degree of flexibility varies depending on the cable’s diameter and construction (1×19, 7×7, 7×19, etc.), the tradeoff for flexibility is strength, and the opposite is also true.

For commercial projects or anywhere there is heavy pedestrian traffic, we recommend a 3/16-inch diameter cable (316-grade stainless steel). It is most commonly used and is durable, low-maintenance, and is attractive. For a variable aesthetic option, other diameters are available from 1/8-, 1/4-, 5/16-, and 3/8-inches.

Stainless-Steel Cable Railing Flexibility

Cable flexibility is an important consideration when designing a cable railing application. The International Residential Code (IRC) and International Building Code (IBC) require that a 4-inch sphere shall not pass through any portion of the installed railing. Because of this code requirement, the use of the most rigid of cable construction possible is ideal. Having the rigidity to prevent deflection of a horizontal run cable subjected to a vertical load is partly mitigated by the cable’s lack of flexibility.

The IBC requires cable designs to withstand a single concentrated load of 200 pounds applied in any direction at any point along the top. Also, attachment devices and supporting structures — handrails and guards — transfer the load to structural elements of the building.

Other factors include the tension — to at least 225 pounds — of the cable, the span between supporting intermediate members, the cable’s diameter, the vertical spacing of the cables on center, and temperature at the time of installation. Temperature fluctuations can cause variations in cable tension due to differing thermal expansion of the railing frame and the cable.  Depending on geographic locations, cable railings installed outdoors may experience large swings in temperatures; hot summer days to the cold winter nights may be a 140-degree difference.

The use of a stainless-steel railing frame virtually eliminates temperature-induced tension changes because it contracts and expands at the same rate as the stainless-steel cable.

Alternative materials like carbon steel, aluminum, and wood each expand differently than stainless and railing frames made from these materials and will exhibit varying cable tension with changes in temperature.

Post Spacing for Cable Railing

Intermediate posts or braces support the cable as it passes through the railing frame’s posts. An intermediate post is a structural post that runs from the top rail to the mounting surface, and a brace is a lighter weight material, supporting the cable and placed between posts.

While cable can run quite long distances (as much as 60-feet or more) between end posts, it will need support at intervals — intermediate posts or braces — to avoid cable deflection in excess permitted by building codes.

It is recommended to space posts or braces at a maximum of 48-inches with center cables 3-1/8-inches apart.

Stainless-Steel Cable Railing Tension and Top Rail

Mounting and tensioning hardware is attached to end posts and work together to minimize the deflection. Posts must not deflect perceptively as the cables are tensioned to a minimum of 225 pounds at heights of 36- to 42-inches. It is crucial to minimize end post deflection, and potential bending, as an incredible amount of force is placed on the end post with ten or more lines.

A sturdy top rail is required to support the tensioning end posts and prevent bending under the strain of the tensioned cables. The most commonly used top rail for commercial use is stainless steel due to its resistance to corrosion and low maintenance.

Designing with Stainless Steel Vertical Railings

Vertical cable railings — cables run from the top rail to the bottom rail — are becoming increasingly popular to differentiate a project for either interior or exterior use. The building code requirements apply to vertical cable railings; however, the installation of vertical railings differ.

Framing material — pipe, or structural square or rectangular tube framing (stainless steel for exterior use) — with a minimum wall thickness of ¼-inch is ideal.  Cable braces are appropriate for replacing every eight cables to keep the top and bottom rails from bending when the cables are tensioned.

In this example, we recommend using the Invisiware® Threaded Stud on one end of the cable and screwed into a drilled and tapped hole in the underside of the top rail. An Invisiware® Receiver inserted into a hole drilled through the bottom rail. A threaded stud on the other end of the cable, tensioned by turning the receiver with an Allen wrench, completes the run.

Stainless steel cable railings and fittings offer a beautiful, low maintenance option to enhance interior and exterior designs. Ultra-tec products also contribute to LEED® credits benefiting architects, designers, and building owners to achieve required building certifications.

Aesthetically pleasing, cable railings offer an impressive installation option for a variety of commercial applications like rooftop decks, interior and exterior stairways, and stadiums where unobstructive views are ideal. Before installing cable railing, however, it’s important to understand how to install cable railing and the recommended framework for a successful and long-lasting installation.

Ideal Metal Frame Variations for Cable Railing

Metal frames and cable railing components, typically constructed using carbon steel or stainless steel, are commonly used in commercial applications for both interior and exterior. While carbon steel or stainless steel are the most common metal frame materials, other can be used. They need to be engineered to meet code requirements and other necessary considerations in the design of a sound cable railing system.

Carbon steel or stainless steel are recommended frames and cable railing components for commercial use because of their outstanding performance in use with cables. In choosing between carbon or stainless steel, it’s important to note the differences to determine what is best to use for your project.

Stainless Steel

Generally preferred for its corrosion resistance and low maintenance, stainless steel is specified typically for its aesthetic appeal for classic and modern designs. It is also resistant to high and low temperatures in most grades while maintaining its strength.

Carbon Steel

Harder and stronger than stainless, carbon steel is an excellent choice for more industrial use where appearance is not an issue. It is subject to corrosion if not coated and can tarnish or rust if not applied regularly. Carbon steel is  ideal for hidden areas and for cost-conscious projects.

Metal Railing Framing Construction

Properly tensioned cables will exert 225 pounds of tension each. A properly constructed metal framing and sturdy top rail is critical to prevent the end posts from bowing when the cables are tensioned. Three metal frame variations we recommend include:

Double End Post Construction

This type of construction is strong, yet its elements are thin enough to have minimal visual obstruction created by the frame. This railing style uses an end post and two vertical members separated by stainless steel spacers. Intermediate posts are only one-inch thick, contributing to a seamless design.

Wall Structural Steel End Post Construction

End posts are slightly thicker for wall mounting; the intermediate posts can be smaller to minimize the frame’s bulkiness.

Pipe and Round Steel Tube Posts

Round tube used with a wall thickness at least comparable to schedule 80 or heavier pipe, or ¼-inch tube wall thickness. Top and bottom rails and intermediate posts constructed from schedule 40 pipe, or a minimum of 1/8-inch tube wall thickness.

Cable Railing Components

We recommend stainless steel cable railing components for exterior applications due to their low maintenance and longevity in extreme and fluctuating temperatures.

Stainless Steel Cable Brace

Since cable runs between terminating end posts can be quite long, it’s necessary to support the cable with intermediate posts or cable braces every 48-inches or less to prevent cable flexing beyond a 4-inch opening between cables (needed per the 4-inch sphere rule for guards). Cable braces come in two lengths, 36- or 42-inch, are ¼-inch by 1-inch and must weld to metal frames.

Stainless Steel Cable Brace Floor Plates

Used for mounting cable braces to the top or bottom rail or deck.

Stainless Steel Spacers

Stainless steel spacers, round, 1-inch in length, and are used to support thin-walled double end post design or allow for receiver extension in a stair system.
