Secure Timber Post Connections for Structural & Outdoor Projects
Building a post connection that has to remain correctly positioned starts below the timber, not at the top of it. Hobson | Post Supports cover heavy-duty post-support configurations for timber construction, outdoor structures & building work where the post needs an appropriate connection to its supporting substrate. Hobson's documented range includes U-shape, T-shape & L-stirrup configurations, with options spanning hot dip galvanised steel & 316 stainless steel across relevant product families.
Choosing the support is only one part of the connection. Projects requiring complementary hardware can move directly into Hobson | Bolts & Nuts, while installations involving concrete substrates may also require correctly specified products from Anchor Bolts.
What Are Hobson Post Supports?
Think of the post support as the interface between the timber member & the structure beneath it. Hobson identifies these products within its heavy-duty post support range, with different shapes, stem arrangements, dimensions & finishes available to suit different connection details.
Among Hobson's documented configurations are:
► U-shape rod-stem post supports
► U-shape with-bar post supports
► U-shape bolt-on post supports
► T-shape rod-stem post supports
► T-blade bolt-on post supports
► L-stirrup rod-stem post supports
► Hot dip galvanised options
► 316 stainless steel options in relevant U-shape families
Dimensions vary considerably between products. Hobson documents U-shape rod-stem supports in widths including 90 mm & 100 mm, with stem lengths across examples from 150 mm through to 600 mm. Other configurations use different dimensions, so a post support should be identified from its complete specification rather than from appearance alone.
Why Choose Hobson Post Supports?
A post support that fits the timber but not the connection detail is only half selected. Hobson's range gives builders, carpenters, fabricators & trade buyers multiple configurations for approaching post-to-base connections instead of treating every timber post as though it needs the same bracket.
The distinction between U-shape, T-shape, L-stirrup, rod-stem & bolt-on configurations matters because each changes how the post is located & how the support interfaces with the surrounding construction.
Material finish deserves equal attention. Hot dip galvanised products are documented throughout Hobson's post-support range, while selected U-shape with-bar products are also available in 316 stainless steel. Environmental exposure, project requirements & compatibility with surrounding materials should guide that decision.
When the post connection forms part of a larger timber or structural assembly, Hobson | Brackets provides a logical next step for related connection hardware.
Common Applications
Timber Posts & Framed Outdoor Structures
A pergola, shelter or framed outdoor structure can place very different demands on its post connections depending on geometry, exposure & design. Hobson post supports provide configuration options for projects where timber posts need to connect into the supporting construction through an appropriate stirrup, blade or U-shaped detail.
The required post section, loads, base material & project documentation should determine the actual support rather than selecting solely by the visible width of the timber.
Deck & Verandah Construction
Post placement becomes much harder to correct once the deck framing starts relying on it. During deck, verandah & similar timber construction, the support configuration should be established alongside post dimensions, footing details, finished levels & the intended connection method.
Where other structural connections occur throughout the build, Structural Fasteners & Bolts can help buyers source complementary hardware according to the relevant project requirements.
Concrete Footings & Base Connections
A post standing over concrete needs more thought than simply choosing a bracket with enough room between the sides. Depending on the support design, the connection may involve an embedded stem, bar or a bolt-on arrangement interacting with the concrete base.
For concrete-related construction work beyond the support itself, Concrete Reinforcement provides a related category for reinforced footing & concrete project requirements.
Fences, Screens & Landscape Structures
Outdoor posts often face exposure from both the weather & the ground-level environment around the connection. Fencing, screening & landscape structures can therefore require careful consideration of post size, support geometry, material finish & the conditions surrounding the installed connection.
A support used in an exposed location should be selected against the actual environmental & project requirements rather than assuming every metallic finish provides the same service conditions.
Maintenance & Replacement Work
Replacing an existing post support is where visual matching can become misleading. Older hardware may have different dimensions, stem lengths, hole positions or material specifications even when the overall shape looks familiar.
Measure the existing connection, identify the timber section & determine how the support interfaces with the substrate before ordering the replacement.
For practical thinking around hardware selection, Why Good Fasteners Matter More Than the Tool You Drive Them With reinforces why connection components should be treated as part of the job specification rather than an afterthought.
Product Selection Guide
Start With the Post Size
Before comparing finishes or stem lengths, establish what timber member actually needs to sit in the support. Hobson post-support dimensions vary by configuration, with documented U-shape examples including 90 mm & 100 mm widths alongside other sizes in the broader range.
Check the product dimensions rather than relying on a nominal description alone, particularly where timber tolerances, treatment, coatings or existing construction affect the physical fit.
Choose the Connection Configuration
The shape of the steel tells you something important about how the connection is intended to come together.
A U-shape support engages the post differently from a T-blade or L-stirrup arrangement. Likewise, a rod stem is not the same base condition as a bolt-on support.
Match the support configuration to the construction detail rather than treating these designs as interchangeable.
Determine the Required Stem or Base Arrangement
What happens below the visible post can be just as important as the steel surrounding it. Hobson documents rod-stem post supports in multiple lengths, including U-shape examples from 150 mm to 600 mm, while bolt-on products use a different base arrangement.
Embedment, anchoring, concrete geometry & installation requirements should come from the applicable project detail or specification.
Where an anchoring system is required elsewhere in the project, Screws & Anchors provides access to broader fixing options.
Select the Finish for the Environment
Two post supports with similar geometry can still be materially different choices once exposure enters the equation.
Hobson documents hot dip galvanised heavy-duty post supports across multiple configurations. Relevant U-shape with-bar products are also documented in 316 stainless steel, including examples such as 90 × 450 mm, 90 × 600 mm, 100 × 450 mm & 100 × 600 mm.
Do not choose between galvanised & stainless products from colour or appearance. Confirm the required material, exposure conditions, surrounding materials & project specification.
Confirm the Fixing Detail
A strong-looking support does not make unspecified bolts, screws or anchors automatically suitable. Hole diameter, fixing type, fastener material, edge distances, substrate & connection requirements all need to suit the selected support & project.
If the build requires additional nuts, washers or related fastening hardware, Nuts & Washers provides a complementary purchasing route.
Comparing Hobson Post Support Configurations
Choosing by shape becomes easier once the actual connection detail is put on the table.

Expert Tips
Set Out the Post Centres Before the Concrete Controls Them
A few millimetres at the base can become far more obvious once a row of posts reaches full height. Establish centre lines, finished levels & orientation before supports are embedded or permanently fixed.
For projects where accurate positioning matters across multiple supports, Measuring & Leveling Tools can help with site layout & verification.
Check More Than the Nominal Timber Size
Timber marked with the same nominal size does not guarantee that every installed condition will be identical. Measure the actual post where fit is important & compare it with the documented support dimensions.
This becomes especially useful during repair work, where existing posts may have weathered, swollen, been dressed or differ from current material dimensions.
Keep Orientation Consistent Across Repeated Supports
Nothing exposes inconsistent installation faster than a straight run of posts with hardware facing different directions. Establish the intended orientation before fixing the first support & carry that reference through the remaining positions.
A simple site check early in the installation can prevent cosmetic & practical corrections later.
Don't Substitute Finish Based on Appearance
Silver-coloured hardware can represent very different materials & protective finishes. Confirm whether the specified product is hot dip galvanised or 316 stainless rather than assuming the two can be exchanged because their dimensions are similar.
Hobson's own product families demonstrate why finish belongs in the product identification, not merely in the visual description.
Treat Concrete Placement as Part of the Connection
An embedded support cannot compensate for poorly positioned or unsuitable concrete around it. Keep the support aligned during placement & follow the applicable construction requirements for footing dimensions, concrete, embedment & curing before loading the connection.

Verify Replacement Hardware Before Removing the Existing Post
A dismantled structure is a poor time to discover the replacement support has a different stem length or fixing arrangement. Record dimensions, photograph the existing connection & identify how the old support is installed before demolition begins.
That preparation gives purchasing teams more useful information than an approximate description from memory.
Inspect Exposed Connections Over Their Service Life
Outdoor steelwork should not disappear from the maintenance conversation once construction is finished. Periodically inspect accessible post connections for movement, damage, deterioration, loose hardware or changes in the surrounding timber & substrate.
Where a condition raises structural concerns, have the connection assessed by an appropriately qualified person rather than relying on a cosmetic repair.
