A Grade temporary fence installs with continuous mesh banners (covers). To support wind loads, fence hire companies use weight, ancillary support braces, auxiliary support stays, clamps and other accessories. This image shows 3 weighted concrete blocks on the fence with a continuous mesh banner graphic attached. This is known as an 'A Grade Install'. Continuous banner is attached via zip ties 500mm apart all edges. Note: 1600mm high continuous banner provides a better wind escape when installed middle vertical plane that offers stability class best wind ratings. Note: Fabric covers fail first, however, if inadequate weighted blocks, slope or ground surface allow fence movement, fabric will fail earlier. Note: If fabric tensioning is too tight, this may cause affix failure due to eyelet pull (eyelets are used to strengthen or protect an opening) and importantly, covers must be removed before high winds occur.

A++

This images shows fence and banner setup for strongest results when attaching banner mesh wrap or trade printed banner signage onto a temp fence location, A++ block method gives great results. The Temp Fence utilizes clamps, perpendicular block, hook stays and 6 x 32kg concrete blocks. Primary, Ancilliary and Auxilary. Eyelets are positioned every 500mm apart and the banner advertising is attached using 4.2x250mm Zip ties (cable ties). The banner size is 1600 mm high which when tied to the topmost horizontal member affords a lower 'wind escape'. Material to use is either Double Coated 9x9 or Double Coated 12x12. 6x6 is not recommended.

C Grade - Open Spans

Open spans are not suitable for banner or hoarding attachment. The C Grade (open spans) temporary fencing install for attaching banner mesh or hoarding materials is not recommended and may not achieve standards. Unsupported banner tie points, a wide span and high risk of failure. Open spans are not suitable.

Width 4.8 mm Standard Zip Tie Strength Chart

These 4.8 Series cable ties are the most popular ties among so many sizes. Most users will prefer to use them, instead of using the smalls size or the big sizes. 4.8 mm wide is called the standard.

We use and recommend DOUBLE LOOP ZIP TIES for installation. Main loop locks tight onto the fence cross member or vertical wire etc, the secondary loop allows soft tensioning of the banner.

Perimeter Edges - Double Reinforced Hems

Double reinforced heat sealed welded edges offer strongest perimeters on all side. This makes a banner wrap fence application better. Technique HOT PLATE WELDING (Hot Wedge) Custom made machine for tempfencebanners.com.au

Included in the TFB mesh banner fence wrap material is a warf diagonal locking stitch that prevents tearing or ripping, heat sealed reinforced edges all sides, double coated PVC better GSM print and durability. This is a great material that TFB mill ourselves so we meticulously check parameters such as 'white point', structural thread strength, Forward-Line Patterning and over 24 QA assessments to ensure trade quality assurance as later purchased and warranted by trade resellers and trade buyers.

Important Design Note: Eyelets

All our machined Eyelets are Stainless Steel Eyelets SS304 sized 21mm OD 11mm ID or Knickel Plated so never rust, crack or break. This allows hex head teks screw fitting, stitching screws, self tappers etc with washers. Do not over tension eyelet fasteners ie. Zip ties or Screws or other.

Important: Inks

This color set is kept common however may vary without notice. NOTE: Production processes may result in different color output than stated: We do not provide color matching facilities and all output manufacturing is via ESTABLISHED DEFAULT PROFILES. Other manufacturing influences are not taken into consideration.

Hirer Notes:

Support Stays & Accessories provide extra bracing strength to help prevent your temporary fence from falling over. This is often required to keep your fence upright and to keep to Australian Standards, if materials such as; shade cloth or advertising materials are added to your fence, Support Stays & Accessories can be used individually or in conjunction with modular support accessories for strength and stability.

Wind-driven airflow

Wind-driven airflow, or natural ventilation, is calculated using the volumetric flow rate equation: Q = C x A x U, where Q is the volumetric flow rate, C is an empirical coefficient, A is the area of the opening, and U is the wind speed.

Empirical Coefficient (C):

Wind-driven airflow, or natural ventilation, is calculated using the volumetric flow rate equation: Q = C x A x U, where Q is the volumetric flow rate, C is an empirical coefficient, A is the area of the opening, and U is the wind speed.

• Volumetric Flow Rate (Q):
  This represents the amount of air moving through an opening in a given time, often measured in cubic meters per hour (m³/h) or cubic feet per minute (CFM).
• Empirical Coefficient (C):
  This factor accounts for the efficiency of wind-driven ventilation, considering factors like wind direction relative to the opening and the shape of the opening.
• ASHRAE recommends a C value of 0.5-0.6 for wind perpendicular to the building openings and 0.25-0.35 for diagonal wind.

The coefficient of effectiveness, K, in the equation Q_wind = K • A • V, is a number from 0 to 1, adjusting for the angle of the wind and other fluid dynamics factors.

Area of the Opening (A):

This is the size of the opening through which the wind is entering or leaving, measured in square meters (m²) or square feet (ft²).

Wind Speed (U):

This is the speed of the wind, typically measured in meters per second (m/s) or kilometres per hour (km/h) or knots per hour (kts).

Example Equation:

Q_wind = K • A • V, where Q_wind is the airflow volumetric rate (m³/h), K is the coefficient of effectiveness (unitless), A is the opening area, of smaller opening (m²), and V is outdoor uninterrupted wind speed (m/h).

Units and Conversions:

• Wind Speed: Common units include m/s, km/h, mph, knots, and ft/s.

Airflow Volume: Common units include m³/h, CFM, and litres per second (l/s).
Area: Common units include m² and ft².

Factors Affecting Wind-Driven Ventilation:

Wind Direction:

The angle at which the wind hits the opening significantly impacts airflow.

• Building Orientation:

The orientation of the building relative to the prevailing wind direction influences ventilation effectiveness.

• Opening Size and Shape:

The size and shape of the opening affect the amount of air that can pass through.

• Presence of Obstructions:

Buildings, trees, and other structures can disrupt airflow and reduce ventilation.
