Application of this Design Guide
and Capacity Tables
NelsonPine LVL is Structural Laminated Veneer
Lumber manufactured in accordance with AS/NZS
4357:1995 Structural Laminated Veneer Lumber by
Nelson Pine Industries Ltd, Nelson, New Zealand.
This Design Guide and Load Span Tables have been
prepared to assist designers and builders in the
selection of NelsonPine LVL beams for the majority
of the common structural applications in residential
timber framed construction and similar timber
framed buildings.
Reference should be made to NZS 3603:1993 Timber Structures Standard, NZS 3604:1999 - Timber
Framed Buildings, or a Structural Engineer
experienced in timber construction for details and
methods of developing lateral restraint, providing
adequate support, anchorage against wind uplift as
well as overall stability, which are outside the scope
of this publication.
Substitution
All Load Span Tables in this document are designed
using the in-grade tested properties of NelsonPine
LVL. Other LVL products may have different
properties and therefore cannot be designed using
these Load Span Tables.
Copyright
Copyright of this publication remains with Nelson
Pine Industries Ltd and reproduction of this
publication in whole or in part without written

NelsonPine LVL is an engineered wood composite
made from rotary peeled veneers, laid up with
parallel grain orientation. One of the main features
of LVL is to disperse or remove strength-reducing
characteristics of wood. NelsonPine LVL
is an engineered, highly predictable,
o n
uniform lumber product, because
natural defects such as knots, slope of grain and
splits have been dispersed throughout the veneer
assembly or have been removed altogether. In
addition to this, the veneer sheets are placed in a
specific sequence and location within the product to
maximise the potential of the stiffer and stronger
veneer grades. This can be considered as an
engineered configuration of the veneers.
NelsonPine LVL properties are consequently superior
to those of glued laminated timber (glulam) and
stress graded timber. The average of most strength
characteristics is higher and the variation is
significantly lower when compared to solid wood.
NelsonPine LVL is dimensionally stable and resists
warping and twisting and is machined to
consistently uniform sizes. NelsonPine LVL is
therefore a high quality product that is more uniform
and exhibits much improved structural properties
over sawn timber.
Manufacture
NelsonPine LVL is manufactured by laminating
ultrasonically graded radiata pine and Douglas Fir
veneer sheets, using phenolic adhesive, in a
continuous assembly in which the grain direction of
the veneers are orientated in the longitudinal
direction. In some instances, cross band veneers
may be introduced. Using highly sophisticated
continuous belt pressing technology and microwave
pre-heating, it is pressed as a 1.250 m nominal width
continuous billet in various standard thicknesses. It
can be docked to any specified length and ripped
into standard widths for use as structural members.
Structural reliability
The structural properties for NelsonPine LVL have
been determined by testing in accordance with the
requirements of AS/NZS 4357:1995 Structural
Laminated Veneer Lumber.
NelsonPine LVL is manufactured by laminating
selected grades of veneer in a predictable pattern in
order to impart predictable, uniform and reliable
structural properties. The uniformity of NelsonPine
LVL is the key to its high strength and stiffness
properties and its reputation for reliable and
predictable performance.

Strength reduction factors
for use with NelsonPine LVL
The strength reduction factor (ol) for calculating the
design capacities of a structural member depends upon
the type of structural material and the application of the
member. NelsonPine NZ LVL 10 used as a structural
element in houses or as a secondary structural element
in structures other than houses has a strength reduction
factor ol of 0.9. For other structural applications, the
value of ol should be obtained from NZS 3603:1993. All
tables in this document have been prepared with the
strength reduction factor of ol = 0.9.
Floor performance
Consideration for flexural deflection and dynamic
behaviour has been made in the design of the allowable
spans for flooring members given in this publication by
limiting the deflection from a 1kN point load placed at
midspan on the floor member to 2mm.
However, if the designer’s experience has shown that
floors designed in accordance with NZS 3604:1999 are
too lively or display excessive deflection, measures
should be taken to improve the floor performance.
Generally the easiest way to achieve this is either to use
larger joists and bearers or to reduce the spacing
between them.
Deep joist restraint
For deep joists, i.e. where the depth of a floor joist
exceeds four times its breadth, continuous blocking or
strutting must be provided at mid span in compliance
with clause 7.1.2.3 of NZS 3604:1999. With NelsonPine
LVL this is often likely to occur, as the product is
applicable to long floor spans giving large open spaces.
For deep joists, the provisions of NZS 3604:1999 are to
be considered a minimum, with the following
Using double section beams
The use of double section beams (except pole bearers)
relies on the effective load transfer between members
in order to ensure that the two beams act together as a
single member.
As a minimum requirement, double members should be
nailed together with 2.80Ø nails, one from each side at
200mm centres along the length of the member. The
nails should be staggered over the depth of the beam
and their lengths should be sufficient to penetrate more
than 90% of the combined member thickness. The top
and bottom faces of the individual members must be
carefully aligned to ensure that the applied loads are
equally shared between the two members.
Where a double member is supporting another at right
angles to its span, the minimum requirement for nailing
will not be sufficient to transfer the loads in the
immediate area of the beam connection. For this type
of arrangement, suitable proprietary fixings can be used
(e.g. joist hangers, multi-grips, etc) provided nailing to
the combined members is with nails of suitable length
to penetrate more than 90% of its combined thickness.
Bearers for pole frame
construction
Bearers for pole frame construction must always be
used in pairs, tied together, one either side of each pole
support. At each support, adequate bearing must be
provided to transfer the loads from the bearers into the
poles. This can be achieved by either notching the pole
or using a steel angle as shown below. The minimum
bearing areas required are given for each member in
the relevant span tables.
BEARING AT SUPPORTS
adjustments:
Steel
Permanent Blocking Permanent blocking is
required along all support lines between every second
joist spacing to assist with buckling restraint and lateral
load transfer to the walls below.
Temporary Restraint In addition to the permanent
blocking, a temporary batten with blocking at each end
is required at the joist midspan to prevent the joists
rotating prior to placement of the flooring. This can be
removed once the placement of the flooring material is
under way.
Temporary blocking each end

Notch
Steel Angle
The bearing surfaces must be in good quality, firm
timber and the bolts should be designed to support all
or part of the applied load. We recommend that the
connections be designed by an engineer.
Fixing of NelsonPine LVL 10
All fixings for NelsonPine LVL members are to be in
accordance with NZS3604:1999.
Where NelsonPine LVL is to be used for applications
other than residential dwellings, the joint design is
required to be by specific design. NelsonPine LVL 10 is
to be designed for the joint group JD5 characteristics.
Rip sawing NelsonPine LVL
Permanent
blocking over

6
One of the unique properties of NelsonPine LVL is that it
may be ripped through the thickness to the smaller
standard section depth given in these span tables
without affecting the basic strength properties. It is
important that the new members are not cut undersized
if the maximum spans in these tables are to apply.
Rip sawing through the depth to produce sections of
reduced thickness may adversely affect strength
properties and is therefore not recommended under any
circumstance.
Minimum bearing lengths
The span lengths provided in the tables are generally
governed by limiting deflections and bending moments.
In order to achieve these spans, the bearing length at
the supports must be provided where specified in the
tables. For continuous spans, the bearing lengths given
with each table are for the internal supports. For the
end supports, the minimum bearing requirements
specified for single span members should be satisfied.
Similarly, where an overhang is required, at the support
between the overhang and the adjacent back span the
minimum bearing lengths for the continuous span
members should be adopted.
Supporting structures
The NelsonPine LVL members given in this publication
are intended to replace standard timber framing
elements in residential construction, albeit with superior
characteristics and hence fewer requirements for
supporting elements. As such, increased importance is
placed on the requirement for satisfying the lateral
strength of any dwelling in which these products are
used. The stability of the structure as a whole must be
checked to ensure that there is sufficient bracing
capacity to resist earthquake and wind loads, in
accordance with the relevant document for the type of
construction being adopted (e.g. timber cladding,
veneer cladding, etc).
Due to the larger floor and roof spans achievable by
NelsonPine LVL, care should be taken to ensure that the
load paths required are present for transferring the
loads to the supporting walls.
For the lintel and bearer tables, it should be noted that
no allowance has been made for the support of heavy
veneers such as brick or solid plaster.
Exposure to humid
conditions and weather
Exposure of NelsonPine LVL to the weather for a limited
time when framed into a structure is not a problem and
will not result in any structural damage. Exposure to the
weather for longer periods could result in some swelling
and discolouration, depending on the conditions.
Durability NelsonPine LVL manufactured from
Radiata Pine veneer bonded with Phenolic adhesive has
a durability rating of Class 4. Whilst the phenolic bond is
fully waterproof, untreated NelsonPine LVL may decay
where the equilibrium moisture content is likely to be
above 20% for extended periods.
In order to eliminate the possibility of decay for subfloor members and flooring, it is good building practice
to ensure that raised floors have adequate clearance
and are well ventilated underneath.
Roof overhangs Provided an adequate protective
coating is applied, NelsonPine LVL beams can be used
as rafters for overhanging covered eaves.
External use Untreated NelsonPine LVL is not
recommended for permanent direct exposure to the
weather, or to high humidity interior conditions, such as
aquatic centres and swimming pools. NelsonPine LVL
should not be used on Pergola’s or Balcony floors,
unless adequately protected with a waterproof
protective coating.
Storage and handling of
NelsonPine LVL
LVL expands in thickness and depth when allowed to
get wet.
To ensure the full benefits of NelsonPine LVL as a dry,
straight and true material are available at the time of
installation, the following recommendations regarding
storage are made:
1. Stack on evenly spaced level bearers to keep flat
and straight.
2. Stack well clear of the ground for good
ventilation.
3. Store under cover to keep dry prior to installation.
4. Take care to re-wrap remaining material after
opening bundles.
5. Use 100 x 50 timber bearers on the flat between
bundles.
Holes in floor joists
Holes in uniformly loaded floor joists (excluding
overhangs) are to be in accordance with the
recommendations made in NZS 3604:1999. Clauses
7.1.7.1 and 7.1.7.3 state that “Holes drilled in floor joists
other than cantilevered joists shall be:
a) Within the middle third of the depth of the joist;
b) Not more than 3 times the depth of the joist from
the face of a support (to the far side of the outer hole).
c) Not more in diameter than one-fifth the depth of the
joist or 32mm, whichever is the lesser;
d) At minimum spacing measured along the joist
between the edges of the holes of not less than the
depth of the joist.”
If holes are required in floor joists outside the scope of
NZS 3604, specific engineering design will be required.

Flooring Material - The above tables allow for a timber flooring material only. Where a heavier overlay material, such as a mortar bed with a tiled
or slate floor is to be applied, the dead load will increase. The 40kg/m2 table can be used for dead loads up to 70kg/m2 by adopting the maximum
spans for 600 and 450mm spacings, but installing the joists at spacings of 450 and 300mm respectively.
Overhanging Joists - For overhanging joists, continuous blocking at the cantilever end of the joists is required. The overhang distances given in
the table are to be treated as maximums, with the limitation that no overhang is to be greater than one half of the adjacent back span.
Concentrated Loads - No allowance has been made in the above tables for concentrated loads from load bearing walls above.
External Use - Where overhanging joists are to be used in an external application such as a balcony, the members must be fully protected from
the weather, or treated to an H3 level.
Floor Stiffness - The overall stiffness of the floor system can be improved by more effectively fixing the floor material directly to the joists, in
addition to nails or screws.
