9 Timber Truss Styles

The basis of timber truss design concepts.

Usage of timber frame trusses is highly dependent on the houses (or structures) square footage, roof lines (both pitch and context of other rooflines) overall spans, design preferences and structural requirements. Each truss style can be modified heavily, but these classifications will fit most timber trusses in the post and beam world.

Although it may seem difficult, it’s actually pretty easy to get started on including gorgeous timber trusses in your project. The first step is to review potential truss styles and choose ones that catch your eye.

Simple Truss

Attractive traditional truss, best used in smaller applications. The size of the simple truss is limited to the load bearing capacity of its members, since it doesn’t have webs; this means your typical simple truss span will max out around 30′.

Scissor Truss

A variable slope timber truss with multiple webs and a lot of flexibility. Throwback style truss which still fits in well with modern building styles – especially useful for roofs with different opposing slopes.

Queen Truss

The queen truss frame calls to mind Craftsman or European timber framing design. This special truss design also balances well if you have a tall space to fill. Also, the queen truss allows for display or storage space within a timber truss.

King Truss

A popular and well-liked timber truss style for timber framing – with wide variety of web styles etc. You will need to consider factors such as wall height, room volume, truss spacing and roof slope to arrive at the best variation of the truss for your situation.

Hammer Beam Truss

This heavy truss style can be used for bigger applications like a church, park pavilion or indoor pool space. The Hammer Beam Timber Truss has a special advantage that makes it work especially well in areas of big volume.

Arched Truss

Top cords are not arched but the bottom cord and webs can be placed in a wide variety of arched truss styles. Comes out of the Classical, Euro, Traditional and in some cases Rustic timber frame designs.

Cable Truss

This is a versatile truss that fits well in many situations. Sometimes a full timber truss is too bulky or an industrial timber frame look is desired. This truss can even add a modern touch to old farmhouse for an eclectic aesthetic.

Mono Truss

The mono truss can be easily adjusted to be a scissor mono truss if desired. Space intimacy is the biggest reason to slope the bottom chord of a mono timber frame truss. Can be used in a vaulted ceiling that terminates at the beginning of an upper level or overlooking a great room.

Box Truss

This timber truss can fit into both Traditional and Modern style homes or businesses and shops. The Box Truss can help fill up space in higher ceilings.

These are not your average ‘framer’ wood trusses. These provide the exposed truss experience that signifies such strength, whether you’re sticking with straight timbers, or going with more of a curved look…curved arches, curved braces etc. Keep in mind though, not to get too set on a certain design, because building practicality always influences the truss design you end up choosing. Yes there are other trusses like the gambrel or cruck truss In some cases, building codes and truss engineering will call for changes to be made.

Our timber truss options provide massive visual appeal, with many options in beam sizing and placement. Structural, or non-structural trusses can be used for both stick-built or full timber frame homes.

Avoid the ‘Hail-Mary’ Approach

Gorgeous timber design results in big smiles every time, but trying a ‘lick-n-stick’ approach can actually detract from the overall appearance. The overall design, size ratios, roof lines and context will have a massive effect on your finished product.
