Full Bullnose Edge Profiles
Edge profiles for natural and engineered stone materials contribute to the overall look and feel of a design project. You might not think of it as an important factor in the the design style, but the edge profile that you choose can really impact your kitchen’s appearance. It might be a feature that few people consciously notice, but edge profiles make a world of difference. So let’s focus here on the Full Bullnose edge profiles. We will consider its appearance first. Afterward, we will delve into some specifics regarding this edge profile for stone materials.
Full Bullnose Edge Stone Profile Features
There is a variety of variants in the “bullnose” edge profile family. Fabricators use half bullnose profiles and demi bullnose edge wheels in addition to the full bullnose edge profiling tools we are discussing here. Bullnose edge profiles share a common shape with one another. However, they differ slightly in appearance.
The Full Bullnose profile as it relates to stone materials is defined pretty universally among stone fabricator and other stone professionals. In other words, if you talk to various professionals in the stone industry, you will find that the description and definition of “full bullnose” is the same no matter who you talk to. So what constitutes a full bullnose edge profile? We’ll explain this edge profile for stone by means of an example.
Let’s say you are going to put an edge on a stone slab that measures 40 millimeters thick. You want the edge to consistently curve from the top to the bottom of the slab evenly. In other words, you want the edge of the stone countertop to look like it is an exact semi-circle. To get the edge that is shown in the above rendering on a 40mm thick stone slab, you would need an edge profiling wheel designed to make that edge. What would that wheel look like?
Well, for starters, the part of the tool that removed stock from the edge of the stone would be 40mm tall. Next the tool would have a radius measurement of 20mm; half of the total thickness of the slab. An edge wheel with those specs puts a full bullnose edge on stone surfaces that are the specified height.
Full Bullnose Profile Formula
So no matter which full bullnose edge profile you get, the radius of the wheel will be exactly half of the wheels height. This results in an edge profile that curves evenly and steadily from the top of the slab to the bottom of the slab. So all of the following edge profile wheels would create a full bullnose edge on a slab.
Implied Radius
Here on our website, you will find two different ways of referencing full bullnose profile wheels for natural and engineered stone. The first is way that we reference these profiles (full bull, bullnose, full bullnose, etc.) is by preceding the stone height by the letter V. You might think of this reference style as being an “implied radius” method.
Explicit Radius
The second way you will see us refer to these edge profile wheels is by our using what could be termed as an “explicit radius” method. This convention is just like the previously mentioned way, but the radius is appended to the end. The following table summarizes the specs and the naming conventions we just discussed:
| Edge Type | Slab Thickness | Radius | Implied Radius Code | Explicit Radius Code |
|---|---|---|---|---|
| Full Bullnose | 20mm | 10mm | V20 | V20R10 |
| Full Bullnose | 25mm | 12.5mm | V25 | V25R12.5 |
| Full Bullnose | 27mm | 13.5mm | V27 | V27R13.5 |
| Full Bullnose | 30mm | 15mm | V30 | V30R15 |
| Full Bullnose | 32mm | 16mm | V32 | V32R16 |
| Full Bullnose | 40mm | 20mm | V40 | V40R20 |
| Full Bullnose | 50mm | 25mm | V50 | V50R25 |
| Full Bullnose | 60mm | 30mm | V60 | V60R30 |
| Full Bullnose | 80mm | 40mm | V80 | V80R40 |
As you can see from the table above, not only is the radius easy to figure out, but it really is not necessary to specify the radius of a full bullnose edge profile. However, for the sake of clarity, at times we use the “explicit radius” naming convention in addition to the “implied radius” name.
Full Bullnose Profiles In Real World Applications
Just like other facets of interior design, your edge profile choice will depend on your personal preference. Fortunately, the bullnose edge profile happens to compliment virtually all designs styles. It particularly harmonizes well with styling that benefits from soft edges or curved lines throughout the design. Because this edge profile is gradual and has no sharp corners or edge, is meshes well with “soft” design styles.
Rounded Edges Can Be Safer
Another reason you may entertain the idea of selecting the full bull edge profile for stone countertops is that the design could be viewed as a safe alternative to some of the other stone edge profile styles that are available. Some edge profiles have more pronounced edges and are even “sharper” on the corners. Obviously, there is more to safety than the type of edge profile on your countertop. But it is one less sharp edge in the environment.
Cleaning With Bullnose Edges
Finally, a bullnose edge profile on your kitchen countertop may mean that cleaning off your countertop surface is a tad bit more difficult than it would be if you chose a surface with a more prominent edge or straight lines. Again, this might blend better with your design style. If so, the full bullnose might not be your best option.
In conclusion, the full bullnose edge stone profile is an easy edge profile to identify because of its distinct appearance. It is one of the popular edge profiles and it is a favorable choice for some of the design styles that call for soft lines are muted looking edges. If you are looking for an edge profile that is a bit more distinct than the common standard eased edge, full bullnose edge profiles are a good choice.
